I played from 1am on release night (login servers were down) to about 4:30ish, up again at 7am today, played untill noon and then from 7pm-now (2:38am) and I'm only 1/3 through 82.
If I wasn't spending time with my gf then I'd be nearly 84 by now. Also, playing on a pvp server where its 2-3 alliance vs 50+ horde at every quest hub is slowing me down considerably :l
A horde guild already has 25members at 85 and is already raiding, f**king nolifes xD
