There is a reason I am able to hold aggro on 10+ mobs with 3 mages AOEing like mad and not losing aggro on the mobs in AOE spam groups

Yeah well.

We have identified a fix for an issue that was causing Demoralizing Shout/Roar to generate too much threat when applied to multiple enemies. In addition, we’ve also identified a fix for a separate issue that was causing Battle Shout and most healing spells, effects, and buffs to incorrectly split the threat they generate between enemies that had members of the buffed party on their threat list.
