started day 1 thru WotLK, can't believe how much I am enjoying going back and grinding/working/thinking my way thru the quests and the adventure. Everytime I am close to a new zone, I find running into it, even when I am not close to the correct level. 10k Needles to Feralas and Tanaris, or Stonetalon to Desolace, etc and each time I'm excited about the prospect of eventually questing these zones.
