My largest concern about installing the 1.1 Beta is whether or not they'll be anyone to play with afterwards. I'd prefer not to have to reinstall the game again in order to go back to 1.05. So, what are the player counts like for those of you who have the Beta? Is the sacrifice worth it? Does installing the Beta mean that you can't find games online other than at peak times?
For that matter, has the Beta solved the hosting problems?
