The thing about predicting characters will be OP is that we often forget these Mr. Sakurai Presents videos are ADVERTS. They are designed to subtly trick casual players into thinking the new fighter will be overpowered so they'll buy them to get an edge on their friends, not to give competitive and hardcore players the full frame data and gameplan or anything like that. That's not to say that the competitive community is being disregarded, but they're the periphery demographic for the Mr. Sakurai Presents series, everybody knows the competitive players are gonna scoop up any new character regardless of actual thoughts on them, casual players need to be sold on a fighter if they're not familiar or a fan.
