I'm having an arguement with one of my guild members about the tooltip of Vigilence. Does is gain vengence by the targets damage taken or damage done?
I.e. Do I put it on the top DPS or on the OT?
Edit: Here's the tooltip: "Focus your protective gaze on a group or raid target, reducing their damage taken by 3%. In addition, each time they are hit by an attack your Taunt cooldown is refreshed and you gain Vengeance as if 20% of the damage was done to you. Lasts 30 min. This effect can only be on one target at a time."
