WoW vet here! I've played since the first year it was out (I have had many break though so I'm not totally sad
). I've got an 80 of everything except Warrior (mine is lvl 75) and Warlock (lvl 54). Recently quit as WOTLK wasn't very interesting at end game imo.
Half thinking of going back for Cata, but I'm not sure yet (mostly I just want a Worgan, haha
). I really like how they decided to re-do the old world even if I will miss parts of it a lot.
