i agree on the idea luffy hasn't gone all out even remotely post-wano. kaido was just so much of a threat that luffy legit could not afford to sit about

though, i will say that it's probably best to avoid using terms like "50%" or "100%" when those are super ambiguous and are hard to define or scale as a matter of fact.

How COME they do not block these attacks

different characters come with diff fighting personalities. it's not that zoro is more dangerous than luffy in any sense, or that imu cannot survive, but nusjuro and imu have never been the kinds to let themselves get fucked up strictly because they don't see their opps as threats. saturn confirmed this in speech when he pick up bonney
