In my experience, LFD isn't that bad. It has been relatively enjoyable. There have been few rotten apples in the mix, but don't get into the drama they make. If a healer/tank comes in in pvp gear and you seem to wipe on bosses or maybe even trash, kindly tell them that his/her pvp gear doesn't cut it. Most people I have met have understood and simply left with an apology. If they don't leave, either kick or keep going. a wipe or two more will discourage and make them leave.
Just lower your expectations on LFD. Don't expect to get out of Random Troll instance in 20 minutes, that's just silly. Help the new guys with tactics, that helps a lot more than just rushing in and blaming everything under the sun for the wipe. A wipe here and there? Big deal, run back and try again.
I have yet had an uncompleted ZG/ZA, and longest ones being about an hour.
And if you REALLY detest the very idea of having to explain tactics and such, kindly go with people you know.
Oh, and talk to people. A few jokes here and there and suddenly you are not grouping with robots anymore and you have quite enjoyable experience.
