I’ve looked around a little, and found some mentions of using Lutris, or running it through Steam (tbh I don’t know how that would work), but I’m not really able to find any guide that explains the process well enough. I’m so used to the game being handled by Blizzard’s Battle.net launcher, so I can’t really wrap my head around how that would work.
I could actually install and run it using Bottles, with less effort that Lutris. Though the client can’t load any web resources, and I can’t install anything from it.
