WoW gold is the backbone of the game. Without it, you're an armor less ugly betty. With it, spend WoW gold wherever you want whenever you want. See something selling in the auction house and you think you want it, but it costs 150 WoW gold? Screw it, I buy dumb stuff and give away WoW gold all the time.
