Well its simply

1: Don't be a dick. being a dick cancels out everything else.

2: If i'm tanking and I never have to use living dead, healer gets it

3: If i'm healing and i never have to resort to going into oh fuck mode, tank gets it.

4: If i'm dps, depends who did their job better.

5: goes for all roles, if you don't know how to play your class, don't get snippy when someone gives you advice. example being i had a warrior not long ago that wouldn't listen when i said he should be using his aoe move to stop everyone else from getting attacked.
