Kaido literally used adCoC against scrubbards but never saw anybody clowning him for that
Because Zoro is judged by a higher standard than Luffy.
Like, legit, even his haters do this.
Luffy packs up Lucci with three named Gear 5 attacks after clashing with him? "Lol, Wuffy low-diffed Lucci what a bitch!"
Zoro packs him up with a single name attack after "clashing" with him? "LOL! Why Zoro need KoH though! FrAUdWaTcH!!!"
Hell, they were acting wild for Zoro not one-shotting Lucci with an unamed attack! They judge Zoro by a standard as if he was Roger himself for crying out loud, and even he would probably still need a named attack for a one-shot!
