I was just trying to get this working yesterday on Fedora 42. I have had it working before, with Lutris. All I did was use the configuration downloaded from the Lutris website. Basically it downloads and installs the Battle.net installer with Wine, so you will be running a custom Wine configuration for Battle.net. From there I was able to install and run World of Warcraft. That was about a year ago.
However, when I last tried it this week, I can install the Battle.net launcher fine, and I can log in, but it will keep giving me errors when I try to actually run it and I can never get to where I can actually install any games. The error is something about it going to sleep, but that's about as far as I got.
Hopefully someone else can help.
