Also, how far in the game are you?  Just curious.

I believe I've just started the Mr Sinister mission with Iceman! I reckon I would have probably completed it by now, but I keep buying heroes, getting them to around 15-20, before getting bored and buying another one! Planning on keeping with Iceman though as I quite enjoy using his power set!
