yes its a pure fanservice from Oda.
you have Zoro who can block 2 combined Yonko attack earlier but later you have a hard time fighting Yonko Commander until asspull powerups coming to play.

Zoro doesn't get his feats taken away or made obsolete just because he struggled with King. Big Mom literally admitted she would have to try to defeat Marco who is on the same level as King or potentially even weaker. RT Zoro is far weaker than Big Mom yet he's not supposed to struggle with King just because he blocked hakai?
