I dislike big pulls. It doesn't save much time unless you have some very powerful AoE classes. Most of the time, you don't. The time you save is minimal, but it makes healers one of the most boring classes as all they do is get to press heal and heal and maybe a DoT if they are lucky that the tank uses a few cooldowns to mitigate damage. It makes healer one of the most boring classes to play when you just do wall to wall pulls.
