I'm going to be taking time off work and putting in around 11-14 hours most days. I very much look forward to PVP and murdering the occasional Ally along the way, and I have a great deal of experience with the game but I haven't played that much of the most recent expansions. I'm more than willing to adjust times to match your availability!
Mained a lock in vanilla, hit 60 not too long before Burning Crusades came out, I had a Rogue around level 50 at the time.
During Burning Crusades I brought a Warlock, Rogue, and Druid to 70, had an awesome twink Rogue and druid.
I played most of the other expansions for a month or two on release With Friends, but they never lived up to vanilla and BC. I have played a lot of Rogue, Druid, Warlock, Priest, Mage, and Shaman.
