when you get higher points and become pro your character gets faster and plays more accurate when you play multiplayer against your friends. In tennis i got pro and my mii hits the ball faster, and always wins even when i let others try my mii pro character. In boxing i also got pro and the mii does knockout punches faster than a mii with less skill points. Anyone who plays with my mii pro character gets knockout punches in less than 3 punches. Has anyone else experienced better performance from higher ranked mii characters?
