I was going to post the same thing. With Steam fully backing Linux, I was happy to finally shed Windows. I am primarily a Linux user now, but I still need to dual-boot into Windows just to play Black Ops Cold War.
When I used to play OW, it worked with Lutris, but I haven’t played OW in a long time now. I don’t know the state of OW and Linux. But I really don’t want that kind of experience. I’d love it if Blizzard/Activision start making their launcher and games work in Linux like Steam does. It’d be nice if they leverage Steam’s advanced work on Proton (and perhaps contribute to it too). Not ideal, but if they create their own solution just for their Battle.net launcher and games, I’ll take it.
But please give me a reason to finally ditch Windows! If not, being the only thing that’s keeping me from 100% Linux, I’ll just ditch Blizzard/Actiivision games for Steam alternatives.
