--- Comment #29 from Pavel pavel1r@gmail.com --- I think staging required for WoW and other games to run, but Battle net should be working with stable. So, it should be possible to check it with stable version. What I'm usually doing, is to try and install Battle.Net in new prefix. The problem can be seen during installation.
