I really only have one friend who plays regularly. Everyone else has played at one time, but is off WoW now. Hope it works out for you, I've always wanted to play with a group of people from RL.
It's always fun to play with folks you know IRL. The problem I have run into is when your playstyles don't quite mesh up, such as you being more hardcore, etc.
a couple friends of mine moved to Boulderfist with me but that was short lived. Still haven't gotten the hang of the new server, just playing on there doesn't get me nearly as many census numbers as boulderfist did, for sure. pvp aint that great, but they actually heal during wintergrasp! and even win on defense!
