The beta is currently undergoing some changes, both large and small. To start things off, here is a quote from Tigole:
I've spent the morning playing the hunter. You guys are in for a *serious* treat.
- Plainsrunning is getting fixed, hopefully for next patch. You'll be able to turn it on or off like an ability. More interestingly, Tauren will run on all fours while using their racial bonus.
- The development team is focusing on the Hunter class right now but expect changes and additions all around. Special attention is being put into class balance.
- For game balance purposes players will not be able to eat or drink while engaged in combat.
- Many new micro-dungeons have been added
