This basically confirms what I've been saying all along. Zoro is still YC1 level and people are too blind to see it because ever since katakuri fell, people have been heavily downplaying YC1s.
Katakuri's CoA was on a much higher level than Luffy's and his max AP when he used mogura was so great that Luffy had no choice but to dodge it. Kata could probably injure kaido with Mogura, and Marco could probably injure him with his flames(which Queen compared to a shockwave).
If King has ryuo, as I'm 90% sure he does, I'd be willing to be that he could hold back Hakai for 1 second and nearly die in the process as well.
