Other than the horrendous queueing during the afternoon in Frostmourne and occasional, I'm enjoying the game a lot so far. Questing from 80-85 is a lot of fun and the quests are all pretty simple with very interesting storylines.

As for the new races, I dunno if its just me but the Worgen area is really crappy to me. I dont like the story, dont like the way the mobs are placed and the quests are pretty bland. Havent tried the goblins to comment on it tho.
