I'll happily play with anybody, no matter if they aren't geared up quite enough or how knowledgeable they are. As long as they're willing to learn from there mistakes and they can follow basic directions, I'm happy. If they don't fit that bill, they get one chance to change, after that . . . either they or I go buh-bye.
Remember, the only reason you shouldn't me marking up the mobs for the kill order and determining when to engage (it's helpful to learn how much mana your healer/casters likes to run with, the priest I play with likes to engage at any amount over 65% and it bugs the hell out of me, but it's a very rare occurrence for him to run out of mana) is if you don't know the instance well. In that case, let someone who is, do it. Don't forget, most of the time it's not that hard to find a dps willing to do something, tanks and healers are harder to find.
