Yep 130 chapters of Wano focused on filler such as Tama, gifters and run piece but no proper backstory or plot exploration. Could have gotten more on swords, Wano and Wano history instead of force feeding as shit like Oden, and on Zoro but instead he decides to write a shite novel outside of the cannon source.
He's finished.
Wano was seriously such a terrible arc.
Oda wasted so much panel time on irrelevant characters or Yamato and Tama. I get she was crucial to control the fodders but come on Oda, we already got it when you showed it the 5th time. You didn't need to include it the 20th time either.
Also, Scabbards took way too much panel time, especially Kanjuro. I thought MF was slayed before they truly invaded Onigashima? Ok, let's say he somehow endured this, okay. Kiku slayed that guy, AGAIN. But wait, somehow he still summoned some black mist wasting panel time AGAIN? Why Oda, why? It didn't make sense at all. Wouldn't it be better if King was spreading the fire instead???
There were just so many pacing issues in this arc.
Franky vs Sasaki would have been great or Jack/Perospero vs Inu/Neko. But no, we got Yamato, Tama, the scabbards and Kanjuro.
Then there are the issues which you also mentioned.
Even the anime with the constant great animation made it very difficult for me to enjoy this arc in general.
