Nice, Blizzard has always had unofficial support for wine. I used to play WoW back in vanilla on Linux using Crossover (or whatever it was called back then.) Occasionally the battle.net launcher will get an update that borks it, but Blizzard has always been very quick to fix it. I play WoW, Diablo4, HOTS, and Hearthstone from Linux. With the recent influx of Linux adoption, maybe Blizzard will release a native Linux launcher. Have to see where things are in the next 5 years.
