I love watching powers collide during an epic fight, think DBZ (Galick Gun vs Kamehameha)....obviously thats a little pointless in this instance but i would like to see certain projectile powers be stopped and spread out if they hit a magical barrier/ward being cast by an enemy NPC or another Player.
It's purely aesthetic and would have no bearing on the game itself, be good to see one day

I second the OP's suggestion!

The idea sounds amazing and could be a possibility in the future, provided it doesnt drop frames to badly. ??
