Sometimes you gotta 'squat n fly'. If you're the one hauling ass and doing healing, that means someone has their backs turned to take damage. When i started playing WHM i'd aero as i'd run which did some decent damage and especially on leves that were +4 so i can imagine the translation in here and i suspect that healers will be the guys to do the worst damage in the ring. That being said this kinda justifies the holy nerf and with cross class abilities we may see even more shady DD healers in the near future depending on PvP abilities/buffs/debuffs (haven't seen 'em all yet).
Just pray Heal Team Six doesn't become the norm.
