mutation mode

okay i love mutation mode... however the biggist issue i see there that should be looked into is ... if a friend of someone is a mutant and the other is still human, the human will run into like a boxcar or something and their mutant friend will block the other mutatnts from getting to him. my suggestion is simply this. if you get turned into a mutant instead of bumping into each other, make it where you go through each other. thats about the only thing i can think of to stop the blocking.
