I don't know about Shanks being second but one thing is sure: He isn't close to Mihawk at all. Mihawk would have dueled him if he pushed him to extreme diff but no he doesn't. He is ready to duel a one-eyed swordsman but not a one-armed one, only logical explanation is Mihawk is a tier above Shanks. Shanks can't push Mihawk past high diff
Most Zoro stans do overall but in this forum people despise Shanks. And now I understand why. He's a pointless bum Oda shoehorns into hype moments. I still love him but I hate the fact I do.
