Some of the strawhats are so unnecessary.
It seems more like they have no role in story anymore
Brook has 0 relevance and wont do shit
Chopper at least gonna cure all illness
Franky perhaps gonna do something important
Zoro just gonna be more strong
Robin just gonna learn about void century (she wont do anthing besides that)
Usopp can be a disappointment
Jinbe is just a guy to fight
Sanji is important
At least, for Nami, oda is cooking her origins
