First and for most I would like to set the record straight on the following: "Healing now applies aggression towards targets aggressors. Example: Warrior A is fighting Mob B. Healer C heals Warrior A and now has aggressed Mob B. (Does not apply in PvP)".
This does not mean that if Tamer A's pet is fighting Mob B and Tamer A heals the pet, Mob B will automatically switch targets to Tamer A. This change only adds healers to the mobs possible target list. In terms of the mob selecting what target to attack, the mobs AI core will always attack the closest visible possible target unless other AI forces re-targeting which is not the norm for example Exodus. The purpose for this change is to help address the long standing issue in which healers were not getting looting rights and improve mob AI.
