I've read a small amount on what this expansion is going to do to the game, but I'd love to hear your overall opinions of how this is going to go. I was much more into Diablo 2 then 3, and don't really know the direction the current development team is taking the game in. I don't have a beta key, so I have no experience with it.

I'm considering coming back for the expansion, but am looking for more details and your opinions.
