I don't see how you take her medals away and not make her garbage. I think she's fine, command grabs in this game are risky as hell. MAYBE tune the damage down a tiny bit, but it probably won't be necessary once people get good.Nah with something gotta shake with the medals or her command throw damage her normals are mad good she has a command grab on roller blades, and her Anti air game is probably the strongest in the game.
I don't even think shes OP but for the way the medal system works for her she shouldn't able stock them up and steam roll with no worries about losing them or acquiring them the current or next round.
