That’s definitely the thing with being a healer, it’s definitely a thankless job. People don’t even notice you until you mess up, or more accurately until you run out of mana while fixing their screw-ups and they die as a result, and Thrall help you at that point. Cause they’ll rip you a new one completely oblivious to the fact that they just took 8x their max HP in damage attacking the wrong boss in Temple of Sethraliss.
I mained Resto up until this patch where I switched to Guardian due to an influx of healers in my guild. Now if something goes wrong in a dungeon and I pull a bit more than I can handle or we body pull something I wasn’t counting on I make sure to either commend the healer for getting us through it or apologize to them if we didn’t make it through. I find that it goes a long way toward making my healers hate me just that little bit less, cause I mean healers naturally hate everyone anyway
