he did not have any reason to fight but being ignored by Marco, whitebeard and stalled by vista was really bad.
Dude, he wasn't trying at all, he had no motivation to fight
Why is it bad?
To me it feels more like you guys wanna make Mihawk look bad, so you focus on that, it's that simple
Oda's powerscaling was shit during Marineford, he set what would be the "top grade power" in Marineford pre-TS, but then after the TS the powerscaling just completely took a shit on what Marineford had in store
Many characters like Marco, who the community made fun of because of Marineford, started getting more powerful and respect once they showed up again in the Post-TS fighting
Same thing will happen to Mihawk, you just have to wait
It makes zero sense for Zoro end goal dream, the fight that has been built up since the first chapters of the story, to be a fraud like so many Mihawk haters want to make him look like
If Mihawk is Zoro's final fight, that means Mihawk is at least stronger than what Zoro is right now, and since Zoro is YC1 level, that puts Mihawk at around Admiral level at least, but only Oda knows how much stronger he wants to make Mihawk
it's that simple, just wait
