one thing I notice on Frostmourne though is the long queue before you could get in the server (it's always full)...this happens mostly on the evening (Phil time)...but I think this is good as finding a raid or instance group is easy.....during afternoon time (US West time) the server also has some queue but not that much...may be 1 min is the longest. Overall, it's good...made my 3 successive runs on WC last night.
