Right I get what you saying, but when I say "threat building", I meant I am 100% aggro with no one above me and it increases the difference in aggro between me and the 2nd on threat. Ex.: I am at 100 threat, I use taunt now I am 105 threat.
You guys have been super helpful, but I have one final question. With the release of 1.2, is there any way to show threat (like the Omen addon in WoW)? In-game settings or addon?
