The "say thank you" was the big one for me. 70% of the time I log on I get a wisp from someone asking to do heroic/5man, meaning use me as a free queue, and I'd be less reluctant to do it every bloody time if people actually thanked me for taking them, especially if its something like a normal 5 man that I wasn't getting much out of.

I don't mind helping people out, and being one of the only heroic-rdy tanks in a small guild I should expect a lot of requests, but a simple thank you would make it all the less stressful.

On Being Thankful.

If you don't appreciate us tanks(and healers!); we aren't going to appreciate you. Tanks/healers work a LOT harder than dps at the moment. Healers have to pay attention to _every tiny little mistake_ that a dps/tank does. If there is ever a more thankless task than cleaning up after anybody... Bah, I can't say how much it pisses me off seeing people bitch about slow healers that are drinking. It's insta-kick for me. I. can. not. stand. that. kind. of. rudeness.

The more YOU as a DPS work at keeping YOURSELF at full hp/mana, the faster the run will go and the more your healer will love you. (Incidentally, the faster a run goes, the shorter the DPS queues will be. Queues take "X" long because heroics take "X" long. Anything you, as a dps, can do to lower that time is good for you, as a dps.)

All this goes without saying: if you want us to do more heroics, then you have to work more to make it easier on us. And you can do that in SO MANY ways. Right now the amount of effort I, as a tank (and don't forget our healers!!), have to put into PUGS is not worth the gear, nor the hair loss.
