Lots of entry- to mid-level options (Zoom75 will have extras available pretty soon, MKC75 is currently in group buy, Monsgeek M1 in stock in some configs) but none off the top of my head in the high-end space
I really shouldn't have to link to the environment, right?
ACKSHUALLY CAN I GET A SOURCE FOR THIS
Non-shitpost edit: Thank you for pulling up those links!
Not to sound doom gloomy here, but my reasons for ditching Blizzard games were absolutely not the launcher. I don't think I'll be going back to Overwatch or anything else in their portfolio because of my issues with game development/marketing (PvE in OW2 promises vs. reality, Warcraft 3 Reforged debacle, etc.).
That said, for anyone who still is up on Blizzard properties, having platform choice is always nice. I still play a ton of Apex Legends and love that it's available via Steam rather than just EA's launcher, for example.
