You. Are. A. Retard.
Kaido is the strongest 1 v. 1. By DEFINITION, you need help to beat him.

A weaker top tier needs another top tier to beat Kaido... high diff perhaps? Meanwhile Luffy has Momo and Yamato against Kaido while Marco could join them soon as well. Even then, it's not guaranted how Luffy will fare against Kaido from now on. You're throwing things out of proportion due to a - despite a very impressive one - feat.
