Stay away unless you are a role player or quester, and even some of them might be fed up at this point. If you're main goal is to pvp then i would suggest forgetting this game exists.. At least til something or someone changes at zos but ive been hoping for that for years.
I quit the game roughly 8 or 9 months ago due to the extremely poor performance of the game (horrible loading times, dysfunctional dungeon finder and broken PvP, just to name very few of them). Has anything improved in the meantime or should I save my money?
