Marineford still ended with multiple major character deaths
Onigashima has yet to have a single one. If it ends without even 1 member of the alliance dying then this may go down as one of the worst wars in shonen
What's the point of a war if there are little to no casualties?
"Multiple major character death"
Only 2 died lol, (3) if you count Oars Jr
And those 2 only died on the very end/last stages of Marineford war
i.e when all side plot + main mission is completed.
Wano still has several side plot yet to be finished......Momo, Zunisha, Hiyori, Oroch etc
Kaido himself is far from getting beaten.
Wano is not ending very soon.
Major character will die only at the last stages of the arc. So there's still alot room left for major character to die, some of them are already guarenteed to be die sooner or later
A war that involves All Admirals + All Warlord +
1 Yonko crew + allied crew, and only 2 major characters died in which 1 of these character could escape if not for his own pride.
Let Wano finish first and judge it
And also Izo and Marco are more beat up in Wano than Marineford lol.....which is supposed to be their main arc.
