ps: And World of Warcraft and City of Heroes/City of Villains both use it.  I'm not sure if COH actually keeps track of healing.  I think only radius-heals, if that. Meaning that if WOW does do all heals, describing it in those solid terms will make the article less correct in reference to COH's Aggro. I also believe that COH also ramps up the hate if a particular creature is weak against a particular attack type.  -
