I thought it was a solid expansion pack. I expected no less from Blizzard. Only thing I didn't like is the Dranei. Not sure what it is, but I just don't like the way they look. I explored the beginning area, but was unable to see the Dranei capital. I did, however, see the Blood Elf capital, and it's pretty ****ing amazing. Unfortuantly since I sold my warrior I can't really get into the meat and potatoes of the expansion (ie outland and level 70).
I was uber pissed that Blood Elves can't be warriors. I kinda thought it was a crock of ****, but wars are my favorite class. If BE's could be warriors, I'd probably roll one and get back into WoW. But I'll stick to my outrageously overpowered Paladin for now I guess.
