Until then I wanted to say one thing to all the tanks and dpsers around here (that I sometimes am on some of my chars).
Be nice with your healers.
Seriously people, healing in cataclysm isn't the piece of cake that it was before, now you can really say that The cake is a lie! (ok bad pun)Mana quickly becomes a serious issue for all healers (with level 83 very often you feel the bite even with ICC gear). But more than only mana, sometimes we just don't have the time to get everyone up, esp. when some people stay in poisonous pools or other fiery areas ...
I once had a player complain I let him die while he was standing in a green poisonous ground that a mob put under him ... I healed him ... he stayed ... after 10s he died. I could have saved him, spending all my mana and 50% of my gcds, that should have been used on the tank.
Please everyone, don't be silly, be nice to your healers and help them. Just ...
Don't stand in the fire.
Until later, Peace, and have fun :)
