Well, sure. I am not denying that Roger MAY have other fighting styles.
But for now, Roger has only shown one fighting style (and with a named attack, something WB never did). So, why is it that you can't accept it now? Worst of all, implying we're the fools to believe that Roger swordsman.
And then you go to Manga Logic. Well sure. Even Mihawk said that being PK was more challenging than being WSS. But you can't provide any evidence as of now, so why don't you stop it? When you get the opportunity, you can go all out (and I know you all will, from experience of Ch. 938). For now, swordbois have upper hand.
