There will still be people on this Forum that will deny EOS Zoro even being a top tier himself. He could make Shanks twerk to his Haki, and people would just downplay Shanks to have been nerfed/never have been a TRUE top tier in the first place or whatever other cope they can come up with.
Remember, everything Zoro does automatically becomes downplayed. Prior to him getting advanced conquerors, it was simply accepted that it signifies of Top Tier status. Afterwards? YC+ level feat at best. Same will happen whenever Zoro splits the sky. Yonko level feat prior? Does not matter, Zoro did it, so it automatically is no longer a top tier feat.
