I read One piece manga/spoiler since ennies lobby and believe me I go though many shit, I even see few people dislike Marineford arc or other great arc, but most time the community where had the same opinion, the most part of the community where agree together. However since the timeskip and at most in Wano, you can see splitt of two large fandoms who where never such in a different opinion, usually 80-90% of the community where happy with the arcs, but Wano is a arc where only 50% at best thing it is good, it showing how massive things change and that scared me little that more and more people leaving One piece in the future with sales even falling more and more down....
In my opinion Wanoo has his good points too, I like Kaido and his battles in the raid, but many other characters get handle very poor right now.
