Before I went on break around mid HFC content I used to queue for random heroics as a healer when i was playing my shadow priests or ele sham. And people used to rage at me incessantly throughout the entire dungeon telling me to "switch specs if I'm going to queue as a healer" even though the whole group has been topped the entire dungeon and I'm 1st or 2nd in dps. I never understood what the problem was or how they could possibly complain. It was almost always a non hybrid dps class such as a hunter, mage, or warlock. I assumed they were just jealous. Anyways my point is this is nothing new and people just love to complain.
