WotLK came out Nov last yr.. not 2 years ago.
HAHAHA I've been sober from WoW for 15 months. And after a 10 day trial cause I was bored, I signed up again for another month today!. Mind you I didn't get WotLK like you did.
I'm having fun, but the addiction hasn't kicked in yet. But I haven't been truely addicted to WoW since pre BC.
Hope you don't get too addicted. Blizzard got me back with the Cataclysm expansion preview too....
