@cardes Well, you shouldn't HAVE to pour much energy into it.
I know Destiny 2 is completely unsupported due to anticheat, but WoW, Guild Wars 2, and ME Legendary Edition should run well on Linux. The problem, as you articulated, is that MY experience with those games may be null and void after a recent game update. Look what happened recently with GTA Online :(
And yes, I hear you about the Steam Deck experience.
