Story wise I already dislike Wano. By far the worst arc for me.
I'm patiently waiting for it to end to see if I'll legit drop One Piece.
Story wise I would actually just do it by the end, but if it is solidified that Sanji got the Gohan/Rock Lee treatment, I drop it for suuuuuuure.
Doesn't make much sense to follow a story that chips away most of the things I like about it. :P
But, again, I'm waiting....patiently.
