OK listen...thing is that OP is not getting good. Problem is that when you have manga that can be compared to OP in it's mysterious, in fights, characters and story overall. You can't call the way how OP looks now even close to good. There's tons of not needed content, filler content or other that downplay characters. It's ridducules how right now OP is build up. Characters win battles only because their opponents are absolutely dumb. Instead of finding way how outsmart their opponents, instead of fighting on your limits, SH right now is winning in fight case all of their opponents is dumb. Also it didn't help storywise too, case instead of character development everything was skiped, or was done bad, at the very least. So right now One Piece became cartoonish, because only in cartoons for little children characters became dummie-characters. I mean dummie-character has no real personality, no real feelings...it's fake. SO when you have manga and anime that could be compared to One PIece, you can't just say that One Piece is great now. I mean, now One Piece is loosing to itself. This is not about power up discussion, this is discussion about One Piece becaming Joke, Cartoon for little kids. That is the problem. I mean those scenes like Feeding Gin, like Zeff eating his leg, or dr Hirurk blowing himself...that wasn't something cartoonish. Crocodile, Buggy, Kuro, Arlong was much more dangerous that any Wano dummie-villain. The only one villain who was close to be done well is Ulty...she showed for one second some tense moment, but in next page everything turned into circus.
You know even Circus in anime could be done scary, could be done insane...but Wano is DUMB. And because of that, I've got strong feeling that if arc serious like that could became JOKE, than what exactly made you believe that Last Arc wouldn't be a JOKE too?
