I give you.... the updated Azshara! Of course, let's not forget about Northrend. Bet you weren't aware that storm peaks has been turned into a large, unlit cavern huh? Search for skoll in style! Be forced to hearth to escape invisible walls, it's a mime's nightmare!
(Disclaimer, this post is more than a little bit tongue in cheek and silly. I'd love to see other beta bug screen shots too
Other bugs I couldn't really take screenshot of include:
After taming a pet from a freezing trap, it will remain in the position it was frozen in until it spawns in/called in again. Quite amusing watching your new pet gliding about as if on ice.
Pets will loose 90% of their health each time they are summoned in. This includes when you dismount and when you enter a new loading zone (such as a dungeon).
