How do people spam holy in those large pulls? Every time a tank pulls large in a level 70 dungeon, if I cast holy the tank is usually loses 60-70% of his/her hp by the time holy goes off. I could swiftcast then use holy, but with the animation time the tank is down like 20% and by the time I have him/her topped off and working on casting holy the mobs are no longer stunned and the tank is back down 60% or so when holy goes off again. There's no way I could spam holy during those pulls. Usually I'm spamming cure 2 and weaving in my other stuff because a spam of cure 2 is generally not enough.
