Tech issues
I like WOTLK, but I do worry about WoW in general as it seems to get more bugs and issues in a game that they've worked on for 4+ years. Something in the underlying tech seems to be creaking at the seams.
When everything is explained with "lag" you might want to rethink your approach to it.
What I really want is for "someone" to do GTA World and let you form all kinds of guilds/gangs/corporations/families and plan/execute massive heists, and a bit of assassinations and deliveries on the side.
