No, my point was that they aren't even at the level where they can enter the New World and expect to live. Rayleigh pretty much directly said this. They lost to Kuma and Kizaru without even the slightest bit of effort. They're not just unable to beat these strong people, they're not even able to fight them and live. If Kuma did not have the desire to save them, they would've been killed…and that's with Gold Roger's former first mate trying to save their lives.
This isn't just a little weak...the Straw Hats are VERY VERY WEAK. Top villains? Top villains are the world governement themselves. They wouldn't be ready to take on the World after a time skip...after a time skip, they'll be ready to enter the New World in the same way they entered the grand Line.
My point is, it's reasonable for characters to improve to a point...but invariably people hit snags along the road. Everyone faces this...they improve to a point, then hit a brick wall...it takes more than a little time to break through to continue improving. The Straw Hats have hit their wall. it's time for a time skip.
If they run off these islands now, there's absolutely no way they will have picked up anything meaningful to continue growing.
Why else would Rayleigh have shown up and warned Luffy about the consequences of running of to Sabaody right now? What else could this possibly mean other than, wait, get stronger, then meet up again and go to the New World?
It just doesn't make sense.
A time skip means the "Monster Trio" will still have the crap kicked out of them by admirals and Emperors....but at the very least, they'll be able to survive in the New World.
There is such a tremendous gap between the few glimpses we've seen of new World Pirates like Whitebeard and the level Luffy is now...if he reaches that level at 17 or even 18, it would be ridiculously unbelievable. It's not that easy to get stronger. If he's capable of something so unbelievable, in a way it removes the tension from the story. It changes Luffy from someone who has to work his butt off to get stronger, to a genius capable of amazing feats at such a young age.
It's even implied Gold Roger left the Grand Line and was forced to return later....took 3 years to reach Raftel on his final journey.
Are we really expecting Luffy to clear the Grand Line and the New World in a year or two? Should it really be that much easier for Monkey D. Luffy than it was for Gol D. Roger?
Baaaad story telling is bad.
Not only were the Straw Hats incapable of fighthing back against Sentomaru and Kuma....they couldn't even run away. They're too weak to run away...that should say enough right there. They were too weak to fight so they tried to run, only to find out they couldn't even do that.
