Following my recent experience healing lower level dungeons, I thought I should write a guide to looking for group from the healers perspective.
Firstly, do not expect anyone to know what they're doing, least of all the tanks. Who needs to know boss tactics? Just rush in, right? After all if you die, it has to be the healers fault and then you should utter those immortal words that all healers love to hear "ffs healer" Just because you, as healer, told the tank not to pull when the boss has a certain buff, do not expect him to listen.
As a dps, NEVER hit the same target as the tank and if you can then try and all run around individually and pull as much as you can, so the healer has three "tanks" to heal. Then when the healer choses to heal the assigned tank and the dps dies, don't forget to utter those words "ffs healer".
ALWAYS make sure that you all stand in as much crap as you can find and don't worry if you see your health dropping alarmingly quickly, the healer will spam heal you and if they don't, don't forget "ffs healer"
At all oportunities try and run as far as away from the healer as you possibly can. If you can find a corner to run around, then do it. Stairs work just as well. Don't let it worry you that you don't seem to be being healed and don't forget "ffs healer" when you die.
If you have a speed buff, always use it at every opportunity to get away from the group and healer and then pull the boss when you're so far ahead you're practically in a different instance, so the healer can watch your health drop and be so far away, they arrive in time to res you and mourn your death and don't forget "ffs healer"
And above all, don't EVER forget that it's the healer's fault and make sure you spend the dungeon being rude to the healer, who can't reply becaue if she does, then people will die while she's typing.
