you can't see a story arc don't mean it not gonna happen?
I mean who the fuck are you that you being able to see or not see something should matter for Oda ...
could you see Momo get THIS MUCH story arc when he was first seen in the manga?
did you?
did any one?
doubt it ..
you not being able "to see" means shit ... people get their story arc and Oda would do his job as a writer to make that happen
so yes ,,, all the Yonko would get an entire arc and Shanks would get 10 chapter and die?
there is some thing called "twist" meaning ... some thing that will happen but people can't expect
if you want to be worry about some one , be worry about Mihawk
2 chapter of fighting in last war and get his ass beat by Zoro is the most he can do
a Yonko not getting story arc in yonko Saga
glad to see you are dumb as ever
p.s
Shanks is seeing a world war coming ... 907
he WILL lead that war
enough story arc there for him
