Overall, a little dull and boring. Even then, that's the point of the login screen. It's suppose to be peaceful and calm with this expansion. Even though war is still going on between Alliance and Horde, there's nothing wrong with a little serenity here and there.
Also, the mounts for the pandarens is going to be cool. Apparently, these bulky buggers are dragon turtles. I bet these are the epic version of them and the one with less armor are going to be the rare version of dragon turtles. Either way, turtles as mounts is always cool.
