@Captain:
That's how I saw Dressrosa's issues. Not sacrificing the present in favour of the future, but overdoing things in an attempt to surpass what came before. If you were cynical, you might say Oda was trying too hard. But I prefer not to discourage the act of trying, so I'll say he was trying in the wrong ways, and that's probably why the unique structure of Zou came as such a breath of fresh air.
But see, that's the thing. There was no real need to make Dressrosa another Marineford in terms of chaos. Primarily because that is how Wano Country has been building, which is going to pretty much be his magnum opus arc of One Piece prior to Raftel after all of the build-up it's had throughout the years and is a testament to how much Oda likes Japanese culture (which is evident in several color spreads and the Ryuma one-shot story before One Piece was published). It was mainly a struggle between two things. The first was living up to all of the Doflamingo hype after building him up for so long since Jaya. Which connected to the Celestial Dragons, CP0, Law, and the Riku Family.
But then there's the second part. Building characters and plotlines for the rest of the New World. Because think about it. Right after Doffy falls, the Yonko become the main focus of the story. The big scary Emperors, who have widespread territories and allies all over the place. In order to combat those factions, Luffy had to start getting those assets in the New World. But if Oda spent the time individually giving focus to each source, than the New World was likely to become very dragged out and feel like a rinse and repeat of how the Straw Hats visited islands built up future allies for the Final War pre-timeskip (who can't be relevant yet at this part of the story for obvious reasons). Not only that, but connecting the Revolutionaries to the Straw Hats and revealing Sabo was also pivotal so that they can be organically connected to future events involving the Straw Hats. And not only that, but we had to get more teases towards all three other Yonko crews to build-up their future relevance and plotlines. AND we had to introduce a new Admiral so that the story could start giving focus to how the Marines have changed since the timeskip due to Kuzan leaving and Akainu rising to his Fleet Admiral position. ANNNNNNNNNNND that last point has to connect to the abolishment of the Warlord system that has been subtly building up since Crocodile as well as promote further tension within the ranks of the Marines that will inevitably lead to a Marine Civil War in the endgame of the series, as we can plainly see with the mindset of altruistic Marines who defy orders to pursue benevolent justice like Smoker and Coby. Not to mention give a bit of relevance to the Samurai to segue over into Zou and Wano Country.
So Oda was tasked with not just having to juggle Doflamingo, the Donquixote Family, Law (whose crew can't even be bothered to be relevant), the Riku Family, and certain World Government connections, but also had to shove in Burgess, Sabo and the Revolutionaries, the Grand Fleet, a Big Mom cameo, Kaido's introduction and SMILE plotline build-up, Gear Fourth so that Luffy can have the necessary power to tackle with the Yonko, Fujitora, and Kanjuro/Samurai antics. I mean, just look at the Water 7 saga. You could easily argue that it's pretty much all one big arc that is over a hundred chapters long like Dressrosa. But pay attention that in such an arc, all Oda had to focus on was CP0 and the World Government, Robin, Franky and Water 7 characters, and Usopp. Those were all major things, but still, just those elements took up over one-hundred chapters to get a satisfactory amount of panel-time dedicated to their plotlines and future build-up. Now look at Dressrosa and the corner Oda unexpectedly put himself in with having to juggle so much stuff. And guess what? It not only all takes place in one day due to all of the Tarantino timeskip shenanigans along with one island unlike how the Water 7 saga was split up between Water 7 and Enies Lobby to give steady pacing, but Dressrosa still has LESS than the amount of chapters the Water 7 saga had (Water 7 Saga: over 120 chapters including Aokiji's scenes in Long Ring Long Land, Dressrosa: 102 chapters).
The Straw Hats had to split up so that Oda wouldn't have to worry about giving screen time to half of the Straw Hat crew. He managed to make it work to his favor by having Sanji, Nami, Chopper, and Brook play major roles in Totland, which is great. But even then, you can see how he has to resort to having Straw Hats leave off to other islands like with the Wano Country gang in order to get the plot rolling a it faster and more conveniently due to having deal with this whole entire mess of plot, plot, and more plot. Even with Law, despite how much focus as he had in Dressrosa, he's bound to have more major focus in Wano Country due to the other Worst Generation Supernovas that are print there. We even have explicit confirmation from Oda that the Dwarves were to supposed to have their own island/arc, so you know that Oda had to shove all of these plotlines together for the sake of the plot later on in the story. It was arguably necessary and benefits One Piece immensely long-term, but it still makes Dressrosa understandably wonky. ESPECIALLY in a week-to-week reading basis.
Just look at how Wano Country is most likely going to be as long or even longer than Dressrosa, but has so much build-up already prepped for it so that it doesn't have to deal with introducing as many elements as Dressrosa had to introduce to the story. What was supposed to be the epic Doflamingo arc we all waited a decade or more for ended up having to become a sacrificial lamb for the rest of One Piece. It wasn't a climax arc, it was most definitely a build-up arc. WANO COUNTRY, Kaido's base of operations, is supposed to be the climax arc of this second act in One Piece's overall narrative due to all of the build-up Kaido has had since Punk Hazard and even beforehand in Fishman Island since Big Mom, at the end of the day, is meant to complement Kaido's saga than having anything much beyond her own arc. That is where Luffy is building up forces to attack another huge antagonist force with various factions on each side like the conflict between Whitebeard and the Marines at Marineford.
Do you understand my point now? Just because an arc has to complement the narrative structure surrounding it does not excuse it from not successfully balancing their own individualized story merits as well. Wano Country is supposed to be the next Marineford. Dressrosa just ended up being bloated enough to ironically look like the sequel when, really, it was just building up necessary chess pieces to fall into place with Kaido's downfall. There was no need to for Oda to "test himself" with Dressrosa because it's literally only the SECOND island in the New World. The island right after Luffy formed his alliance with Law, that was made for the purpose of taking down Kaido (even though Law was probably just using that as an excuse to only take down Doflamingo for sure, but its purpose is still meant to play into Kaido's defeat in an objective narrative perspective). Yes, there has to be substantial momentum and stakes kept to make post-timeskip feel like it doesn't automatically revert back to square one like the start of the Grand Line in a redundant fashion. Oda did sacrifice the present for the future, and he really had no choice in doing so. Which is why I don't judge him too hard for it. Besides how the hypocritical pacifism philosophy of the Riku Family, Rebecca's character journey theme, and the Tontattas were dealt with. Those are justified by the rest of the are issues and are just ew lol.
Even with Zou, while it was a breath of fresh air, was just an arc literally focused around exposition for the sake of exposition meant to build-up future plot events. Unlike Jaya and Sabaody Archipelago, which were "breather" arcs that still successfully balanced their own unique non-formulaic arc narratives to be some of the most impressive in One Piece alongside with planting ambitious seeds to be explored for future story events that kept up on our toes waiting for payoff in years to come. Which is why, unlike most others of the forum, Zou doesn't really wow me all that much. Because almost everything that is supposed to grab you about in Zou is, well, everything that doesn't specifically tie into Zou as an individual island with the Sanji/Big Mom, Wano Country/Kaido, Marco/Blackbeard, and Road Poneglyph plot reveals lol. Which is really awkward because Zou was only built-up as a place to pick up the Swirly Hats, the Heart Pirates, and Raizou to then head straight for Kaido.
Dressrosa still has BUNCH of lovably memorable moments, but it's not perfect. And it was never meant to be perfect. Whether or not Oda could really do something about that.

@HeartOfDarkness:
Training arcs are easily the most generic, and laziest ways of "padding" story without any real effort. It's like how Naruto came from a 3 years of training only to have another training arc after that, only to have another training arc after that simply because Kishimoto didn't have any other way of showing the character's growth in ability thus pointlessly doing redundant shit while absolute killing the entire flow. You, as the reader, don't learn anything new by seeing the same redundant training.
MHA is also guilty of this where the writer shoves training arcs between story arcs just because he can't really find a more unique way of showing the character's growth, and it becomes redundant, and boring to read.
Gear-second reveal is something that makes sense for the character, and the story. It shows the growth of a character without having to stop the entire flow, and are pretty damn impactful moments. I very much prefer seeing the struggle of a character in the moment rather than to have redundant scenario's of the same repetitive training sequence.
I wholeheartedly disagree. And Naruto's timeskip relate to issues that are on their own unique class of disorder. I'm talking about arcs such as the Stain arc in My Hero Academia. Where both plot progression is balanced in relation to Stain and Shigaraki, as well as character development and introspection when it came to Deku forming a bond with Gran Torino while learning Full Cowl along with Iida and Todoroki getting developed. I would also like to mention how Deku learned to be less of an All-Might fanboy and find his own identity in the beginning of the Hero License Exam arc by learning to focus on kicks instead of punches in Shoot Style. It doesn't become redundant, it's still entertaining. I would also use Naruto's Rasengan training as a compelling training arc due to how it bonded him with Jiraiya and Tsunade as well as showcasing his willpower and genius through hard work (aside from how it awkwardly shoves the rest of the main cast aside suddenly and the direction the plot takes after the arc).
No. It was shortcutting for the sake of shortcutting. And only because the Straw Hats had to be nerfed in order to generically make CP9 seem intimidating and on a whole other level to build-up hype for the rest of the arc rather than give credit to how strong the Straw Hats already are with suspenseful action where they aren't completely helpless. Training sequences do not and should not be the same or redundant. They can be balanced effectively with plot progression. All Gear Second did was only keep the focus on the plot and give a middle finger to training as if it can only be boring and waste time rather than give great insight into character dynamics, interactions, and growth. Seeing how characters earn their abilities rather than just giving them with half-assed explanations engrosses the audience that much more and makes characters all the more deep and charismatic. Training shouldn't only be about physical development, but also emotion/mental/philosophical development simultaneously. That is compelling. And it would be extremely superficial of you to claim that the potential for that is uninteresting compared to have the plot progress rather than getting meaningful built-up and rushed pacing.
