I'm on desktop, but Heroic and Faugus have worked the best for me. I always had some sort of troubles when using Lutris and Bottles.

I’m running Lutris on desktop and Steam Deck to play WoW. Works fine. Just remember it was a bit irritating to set up the first time with trying to get the Battle.net installer to run properly

I just got the new version on steam instead

I used bottles for a year or two and just switched to Faugus Launcher. Seems a lot more reliable at opening/closing Battle.net for whatever reason.

Lutris works best in my experience for running it. I have battle.net running through proton 10 in it. I think I ended up installing battlenet.exe through steam, then swapping the prefix to the steam-created one in Lutris because Lutris was having issues installing the launcher for me. Wow and D2R work fine, but I haven't tried D4.

Steam was a pain in the butt by itself for me.

I added the setup to Steam, ran with Proton Experimental compatibility, and installed it in that context, then swapped the exe to the installed Battlenet launcher in the same context. After that, I installed all of the games to a separate drive. If I need to reinstall for whatever reason, Battlenet can be pointed back to that location.

NonSteamLaunchers may be the easiest way, but it's no longer on the decky store due to some drama stuff. Instead you download the zip file, unzip it, and then place the whole folder into ~/homebrew/plugins. Restart steam and it should show up.

Otherwise I've used bottles on desktop to install it. Unfortunately Lutris installs are becoming increasingly unreliable in my experience.

I used Lutris for bnet games that are not on Steam, works great with SC2, if you want to force compile all shaders, run the "unit preloader" custom map

I've heard Faugus is good too

I’m currently using Faugus. It has a quick easy installer. My only gripe is that it loads really slow for me and I had to end up turning off hardware acceleration because the launcher lagged so bad.

I tried to install through lutris but the script kept bugging out and forcing me to abort and delete all the files. Not sure what’s up with that.
