Okay, that's a problem.

It mainly depends on what exactly HOW fast the character goes. Superhuman speeds, like, faster than a speeding bullet or the speed of sound, would break the game because in the time it takes for someone to throw a punch, you'd thrown almost ten thousand times that. Not to mention being able to dodge almost anything that heads your way in a snap of a finger.

There are levels of super speed that are acceptable though. From what I remembered, I had a character who could move as fast as a Cheetah in a previous RPG.
