I can agree with some points here, I do pride myself on being one of the few who helps people and doesn't have the elitist attitude of "GO GOOGLE IT NOOB!" However that being said, when you are in a q for hours and finally get into a group only to find that their are new people who drastically increase your chances of wiping it's disheartening. Especially when they have just unlocked the instance and haven't even bothered watching the fight on YouTube or even reading about it.

I still say a cross realm function would allow all these problems to sort themselves out, especially for people on tiny realms with not for population as I am.
