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.
