Yeah, what about ZORO fighting a guy who uses multiple combat categories? Zoro is fighting only a non-swordsman opponent, I don't understand how this argument will benefit him... It's the same as Mihawk fighting Big Mom, nothing stops him, if he wins is the problem. Parting things apart so you and your brain understand: Mihawk can fight Big Mom in a sword duel and be superior, it shows that with swordsmanship he's better, but Big Mom isn't a swordsman, she doesn't call herself such, so if she fry Mihawk using her DF+ powers Espada, the Mihawk will not have the invalid title. King is not a swordsman, so he can fuck ZORO any way he wants, if ZORO loses, his swordsmanship will still be better than KING's, as KING didn't beat him in a spade clash.
If Oden and Mihawk fought and Oden won because of his adv CoC would you say Oden is not the WSS?
