@No:
I know I'm in the extremely small minority here, but I personally wouldn't mind super long fights as a way to keep characters engaged in something during these large arcs with tons of different things happening at once (which seems to be the norm nowadays) as opposed to just having them running around. We could still see the important parts (discovering enemy weaknesses, stating reasons they have to win, reacting to major events, finishing blows, etc.), keeping the skipped parts to "they hit each other for 3 hours without either side making progress". Doesn't Zoro fighting King the Calamity for 5 hours while all the events leading up to the climax of Wano simultaneously take place sound better than Zoro chasing King as the latter shifts through all the stone on the island, causing Zoro to run around like a headless chicken for half the arc before cornering King (plot twist: he was a swordsman all along) and beating him in two hits?
The problem is that whenever this happens, like with Zoro vs Pica and Luffy vs Katakuri, the story drifts away from the fight so much that by the time it gets focus, people aren't that emotional invested in wanting to see the fight anymore. There were so many comments I read when Luffy went back to the Mirror World to fight Katakuri about how the fight felt like it was being dragged, and Zoro vs. Pica was a whole other scale of nightmares. Add in how it becomes harder to remember what happened earlier in the fight and how the plot feels like it has to stop whenever the fight gets focus again, and it's just messy all around. Not completely unbearable, but following a fight straight from beginning to finish like in Alabasta is much preferable.
Zoro stalemating King for five hours while Zoro chases king for five hours are practically the same thing. That fight's problem was how it was separated in-between other events to begin with, not that Zoro playing hide-and-seek with Pica was actually bad (although it could've been much better).
Man, I still can't get erase that memory about Pica using a sword. That was sooooooo unnecessary. Zoro does not ALWAYS have to fight a swordsman. There are other ways to test swordsmanship besides always slapping the island's local swordsman's face with your glove to demand satisfaction.
