For the sake of the story I guess Kaido getting back up would be cool, but damn, as a weekly reader, watching this man fight for over a year has taken its toll and I can't take it any longer. I feel so much relief that it's over and we can finally start moving on from Wano.
Hakai - Blocked for one sec
Ashura - Outshined by Luffy's AdvCoC
Zoro coming back - Had to share it with Sanji and both be Stars
Zoro defeatin King - Beat him when he wasnt using Zoan or Lunarian defensive powers
Sure his feats are great, but Oda did them in bad ways. Couldve been a whole lot better. Even if ZKK were to occur itd be half-assed.....
Man I don't really see how any of these are bad treatment besides MAYBE the Ashura scar
Like Zoro blocking hakai was realistic and still a great feat, Kid even said so himself. If he had just tanked the whole thing without damage it would diminish the actual threat of a combined attack from 2 Yonko. Plus it was pretty much a plot device to get Luffy his 1v1 anyway
I don't really see how Zoro coming back in accordance with Sanji is anything bad, it's only in the eyes of the retards who make literally everything into Zoro vs. Sanji
And lastly defeating King was great, he unlocked ACoC and handled a 1st commander quite easily. The way King's abilities worked was questionable, sure, but there are greater issues with almost every other fight that Oda draws
I'd say the way Oda has treated Zoro in Wano was not bad in terms of feats/fights, it's been bad in terms of his importance
