They mentioned balancing issues before somewhere on the champions site. It was along the lines of: You activate a melee attack that continuously grows stronger until you finally get in range to use it. It's designed to be able to equal up to the DPS dealt by a flier. Still, these things always work better on paper than in motion, so we'll see.

Also, I hope they don't make villains playable. That started off alright with CoH, but ended up killing it for me as CoV was the only side getting any new content and CoH only got rehashed, blander versions of those updates. Also, every hero side power seemed to continually get nerfed for the sake of PvP which, again, didn't help me to maintain my interest.
