The motion sight thing still weirds me out a little bit. So he would be able to read a stop sign behind him? Not sure I understand why it is linked to sight? Not so concerned with the balance on it.
Can you give me an example how he would see motion all around him?
Taking a cue from Ultimate Power what about
Spatial Awareness (4 points): You are mentally aware of
your surroundings, even when you cannot see them. Accurate,
Radius, Ranged Mental Sense.
Sure someone with Concealment vs Mental Sense could hide from you. But I am okay with that.
