You will pry Rescue from my cold, dead hands.

On the serious, though - it's been a useful tool to help save someone at the last minute or assist in proximity-based mechanics (the bomb with whatshisface in Doma Castle, the Rush move from the wooly mammoth in Bardam, etc.) The extremely lengthy cooldown for the skill also means it is not in any way abuseable - at least not to the degree actual trolls would wish it to be.

Also if dps would learn to stop standing in bad, maybe I wouldn't have to use it so much.
