I made one of each. I've played the Worgen up to level 8 or 9 so far. Haven't played the Gobbo yet. I've been spending my time leveling my Blood Elf Hunter.
I started playing WoW a couple years ago to please my wife who is a WoW fanatic. I have stopped and started so many times it's pathetic. My highest level char is a 45 Warrior. Can you believe that I have bought the Burning Crusade, Wrath of the Lich King, AND Cataclysm, but so far I haven't leveled up any characters far enough to actually enjoy the content from those expansions? Ha!
