Shanks is enough to debunk your argument. Oda has desperately tried to hide his strength ans even though he has no feats we can still tell he's top-tier. The problem isn't that Mihask hasn't shown any signs of strength yet. But it's that he has only showed signs of weakness. No Yonko EVER is going to be stalled by a YC3 for like a minute and postponing the fight instead of finishing it immediately. Mihawk finished Mr.1 pretty easily, yet he couldn't do the same to Vista, which would be insanely weird for any Yonko or Admiral, not to mention a character who's supposedly "above Yonko" like Mihawk
So Shanks = no feats and great portrayal = at least top-tier
Mihawk = shit feats AND shit portrayal = fraudulent top-tier

You saw big mom get lolled by jinbei twice, franky, brook and even robin right? She even has adv. CoC. Dont make generalised statements that are complete and utter garbage.
Can you remind me when shanks was the world's strongest at anything?
