I have played wow on linux since vanilla. Maybe we can help you? These days you can just open lutris and type battle.net and hit install. honestly it is dead simple and my FPS i better in linux than the same hardware in windows.
[edit]And now I see this was already answered. By bad. Long day today…
It would probably be the most point and click on one of the gaming-centric immutable distros. I think nobara is basically a shell for gaming that just happens to have a linux kernel so that might be a good one.
I, myself, am old… And I use standard distros due to ancient muscle memory and shell scripts from the age of dinosaurs. Usually debian based. Right now I’m on PopOS for my daily driver and really digging it.
Lutris is a GUI app with normal point and click interface. So even on a ‘normal’ distro I think it may be like 6 clicks to get the battle.net client installed, and then inside bnet you can install wow or hearthstone (and probably the others, but I can’t vouch directly) just as you did in windows.
Lutris will even give you a nice little bnet icon if you want :)
