So, how often does everyone use this ability? More often than not, I simply forget to cast it as the damage is negligible, and the chance of hitting the KB in a dungeon is minimal.

If possible, I would like to see the skill evolve into something like an execute attack. Yes, I am stealing a WoW term and ability, but that is what it reminds me of. Have it be on use at 20% or less HP of the target, and do more damage/healing based on the amount of Wrath you have accumulated. Something along those lines anyway. Currently, I just feel the skill is too weak to really be utilized.
