Why is everyone so mad about the idea of Jinbei defeating Who's Who on this chapter?
I think it's quite possible.
There's a lot more fights to go in Wano compared to Thriller Bark / Enies Lobby how some of you are doing. I think only characters like Sanji, Zoro and Luffy would get multiple chapters for a fight.
That's just how Oda rolls nowdays, there isn't enough time for Straw Hats or fights, all time is needed for Tama.
