I know it’s popular to hate on Wano here but one of the most ridiculous complaints is that there were too many “abandoned” plot lines or that Oda forgot. While I agree that a lot of the execution for the ending of Wano was ass I don’t think Oda forgot about any plot points (other than the Kokeshi dolls shinobu mentioned). Most of the complaints about abandoned plot points are divided into two categories
1. Will be expanded on later and Oda didn’t want to do it Wano (e.g. Rocks flash back will explain more about Kaido and his reasoning in the arc, Ryuma will be explored more later etc.). Now while I think not explaining some these in Wano was a dumb decision they were not abandoned
Or
2. They were never plot points in the first place these usually happen when fan theories are taken as canon or readers misinterpret dialogue thinking it has greater meaning than it does (e.g. Onigashima’s “true name”, Wano Daimyo looking like numbers)
