Aug 12th 2008 2:23PM I have not been to Booty Bay in the beta of WotLK... However, I was unable to mount in Undercity. Hoping they change UC back to being mountable.
I realize that UC was originally a place where you could not mount... but when the "fixed" it, it was a welcome change.
There is also a nice speed buff to death knights when they are running around in there starting area (in the floating citadel).
