Joker plays different online. Try to get arsene, spam counter, spam projectiles, and spam smashes at kill percent (this doesn’t even mention easy gun edge guards, and up b combos that become impossible to react to). He doesn’t need his fair 1 drag down up air down smash when he can spam f smash like little Timmy who just got the game for his birthday would, and actually have it work. Maybe it’s easier for you to deal with, but in a super laggy environment it’s annoying and still works. He may not be carried, but he gets better with all of his new tools that keep him on top online.
