Okay first of all, I've always been healing as Ele in Resto gear in HC's when the tanks are way overgeared to the HC (except the 3 new ICC ones) and almost noone has ever died.
I was in this Gun'drak earlier, everything went fine till we got to the trash before the Less-Rabi achieve guy when the Pala tank started to complain I'm not healing enough, the dude had about 48k hp and his health bar was full almost the whole time and I did heal everytime my LHW would top him up and ofc healed the others accordingly.
The other guys in the group also went against me for not healing him and not being Resto as I've signed as a Healer, I asked them that if noone have died nor was close to death why are they complaining, the tank came with the following statement: I'm going oom because you dont heal enough, at first I facepalmed and I also noticed he was barely using Divine Plea (Yes I'm aware of its cd).
Afterwards when the Dungeon CD debuff wore off I got kicked.
I really wanna know who's wrong here, what'd you think?
Sorry for any bad english btw.
Edit: So much misunderstanding, I'll clear things up.
I heal as Ele spec once I inspect the tank or check his HP and also looking at his tanking, if he's overgeared with above 35k hp I go Ele and just heal and dps.
I DO have dual spec and Resto spec, I go Rest once I see the tank isnt so good or it's 1 of the new HC's (even ToC).
I queue as healer since I do heal and not only dps, as said above I go resto whenever it's needed.
I also have a prot pala and I'm aware of the mana starvation we're having in hc's, that's why you should chain-pull and not spam all your abilities like the dpsers are pulling 9k and the mobs will 1 shot them. HotR + Cons is more than enough to mobs with 60k hp.
