If you are in your 20's, you can forget leveling without frustration in Hillsbrad for a long time. On PvP servers... forget it. Unless they fixed the corpse issue, video lag along is going to be a killer for people with slower machines.
At least the factions are balanced!
I really wish you could change the colors on the tabard. I like the look, but that red tabard is an eyesore against the rest of the Rogue gear.
