Oda has a huge problem, he doesn’t take the needed time to explain and go into detail when he’s called to do.
But god it’s ok having 10+ chapters of useless or boring plots
he isn’t doing it on purpose , it’s just that he can’t write something that has no Luffy involved.
Katakuri loses to WCI Luffy. WCI Luffy gets one shotted by drunk Kaido. Luffy needs 3 weeks Haki training, still doesn't do shit. Zoro scars and bypasses Kaido scales. Luffy gets another power up, AdCoC. Zoro fights King, who's scales he can't easily bypass due to his gimmick. One shots him when he gets AdCoC.
Somehow a YC1 from a previous arc is stronger than current MCs opponents. A Luffy and Zoro that needed 1 and 2 powerups to beat their current opponents.
Katakuri is trash, just like his mother and you mofos just gotta deal with that 💀
