So basically, everybody who thought Kaido was going to rise from the lava have now changed to "the whole arc was rushed!"
I'm not buying it. Wano had the exact same structure as literally every single One Piece storyline before it. The Straw Hats arrive on an island. They meet a bunch of locals in desperate need of their help. They run off half-cocked and immediately get their asses handed to them by the bad guys. They lick their wounds, come up with a plan and then try again. This time it looks like they're going to win, but... whoops, Luffy got beat again. Overly long flashback sequence. The other Straw Hats methodically take down the bad guy's lieutenants. Once all the small fry are dealt with, Luffy pulls a new power out of ass, rallies and beats the big bad while everybody cheers him on. End of arc.
When you say "rushed" I think you mean "unsatisfying." Kaido was hyped to be the biggest bad alive, and he got taken down by a punch that looked like every other punch Luffy threw that day. And the art was clearly a step down from what came before, in layout and character art. (Its crazy how much better the art was in this last chapter compared to the Kaido fight)
Nearly every Straw Hat got a power up. Zolo got a magic sword. Sanji can turn invisible. Nami got a new staff. Robin turned into a giant demon. Chopper.. well, Chopper sucks. Jimbei finally joined the crew, as did Yamato. You could maybe argue that your favorite character didn't get enough time to shine, but no one can argue their favorite character didn't get something.
In other words, shut the fuck up. I fucking hated Wano, I'm glad its over, but I'm not going to make shit up like "the editors rushed Oda!" to justify my disappointment with the arc as a whole. It just sucked.
