Oh buddy....
There are simply too much stuff bothering me on this entire arc for me to care much about who Zoro or Sanji are fighting.
Besides, while some nice folks were jerking off to Roof Piece screaming "WHy wOulD ZoRo gO bAACK to FiGht KiNG?", I was one of those who always stood for the YC's.
Would I have preferred Sanji vs King and the 5v2 top? Yes.
Did it stay that way? No.
Do I like Sanji vs a 1.32B bounty Calamity with a mecha-godzilla+dr. octopus hybrid form? Yes.
Motherfucker even going through a "venom mini-arc".
I've said it before. The main fights are Kaido, King and Queen vs Luffy, Zoro and Sanji. The rest are just filler fights that exist because the side characters need something to do in the meantime.
