Power Collision

http://www.champions-online.com/node/181

The first question was regarding power collision. While I understand it being impractical to keep track of whether or not projectiles collide with one another, I think it'd be entirely feasible to create a power collision system. Two implementation possibilities that come to mind are: when two characters are targeting each other, any power used during the other characters activation time, will collide with the other character's power. Alternately, there could be an option for powers that are automatically used to counter attacks made against the character by being used in response to and colliding with incoming attacks. My biggest concern would be 1v1 fights turning into stalemates where all attacks are blocked by the other person's attacks.
