Is he supposed to be scared every time he's on panel to prove it was fear? It was fear, get over it. Zoro humiliated Sanji's opponent.
If a swordsman's Doriki is the same regardless of whether it's measured with a physical blow or a sword attack, then that would mean Zoro's punches > Luffy's punches and Sanji's kicks because he shits on both of them in AP.
Lol no, Zoro has been stronger than Luffy since the timeskip. Luffy was a little lower than YC1 at the start of Wano (because Kata let him win) and he got one shot by Kaido and did no damage. Zoro tanked multiple attacks from Kaido, perma scarred him, and saved Luffy's bum ass multiple times on the rooftop. By scaling, he's already above every YC1 by a good margin. Zoro shat on Luffy in feats on the roof.
