Hey, not all is lost..
While it's sickening, there are ways, like the ones I've posted, GPU passthrough (I mean, those walkarounds should be unnecessary, considering that... (drumroll) old launcher for mac already was using CEF https://github.com/ValveSoftware/Pro...ent-1042099897)
But, it's better to have M$ bloated spyware called Windows in the contained VM, while having its capabilities, than to lose the pleasure of such great MMO - and let's be honest - we're a niche. Especially when WoW players like the M$ SAM (geddit?) in topic here are flowing the servers with their crap.
Other than that... either Wine devs will take their effort to support, so inverse enginee ran outdated M$ tech, or SE will bring back old launcher with updated JS, or they'll make a whole, new one, using new, open source tech (or even the CEF they're using thus far for Macs)
Hard decisions.
