I don't really run into problems DFing as a healer (not verbal abuse at least).

The other day, I went to wp hm.. Party was going smoothly, then on the frog pull, I was tossing dots because it seemed the tank was going to stop, but then he went for the door.. And stupidly, I baned while running. I pulled aggro just as he got to the final mobs, which fell into quite a bit of chaos (especially as a flare snagged some mobs, too). I apologized afterm saying I hadn't seen anyone go for that pull in awhile so I didn't expect it... Tank admitted he didn't usually do it, but the past few groups, got harassed for not grabbing both groups. Oh well.
