Seriously, for an 'elite skill', rebound is complete trash. The only useful part of the skill is the aura that you get if the heal doesn't proc, but the 5 second delay to getting that aura makes it worthless. If I'm getting sniped or meleed down, 5 seconds is all it takes for my health to go from 100 to 0. And a 2800 heal is going to do nothing to change that. Imo, rebound should be changed to immediately apply an aura so I have a chance to escape my opponents with shocking/frost aura or reflect projectiles with magnetic aura. Get rid of the heal and the fury for all I care to make it more 'balanced'.
Alternatively, give us an elite skill that isn't trash on one of the weakest pvp classes in the game.
