That excites me, as I've had really inconsistent experiences with Heroic. Them being able to standardize everything so it's running against Steam's runtimes hopefully helps with that.
I answer support requests on the Heroic server. Most game issues are because people are using Proton and not Wine-GE. Heroic now also is auto-installing dependencies after enabling the option
I'll have to take another look at it when I try it again, but for now it's just not anything I'm worried about, since the game I was using with Heroic I just picked up on Steam instead to make it simple LOL
