If anything it's an example that games can be amazing on macOS, if developers take the time to learn and use the system. WoW on macOS is a far superior experience to WoW on Windows.
Also I really can't think of the way Mac's mouse settings in WoW work better than the Windows ones. Scrolling, mouse movement are all having more settings under Windows to customize them compared to the experience on Mac (even with all the tools such as Mos to help with the bad external mouse handling in Mac).
So what exactly is so superior? I play WoW on both platforms and when I have a choice (that is, when playing at my home desktop - on my summer cabin I only have the Mac option) it's always the Windows one I select. It's nice that it works in Mac so I can play everywhere as I only have Mac laptop, but the sometimes weird graphics bugs, worse performance and odd issues with rendering displacing my WAs and other stuff just doesn't inspire confidence in Mac gaming compared to using Windows. And the mouse movement.. ugh.
WoW on Linux with wine used to be a superior experience to WoW on Windows. Because the system didn't lock up for half a minute when I alt-tabbed.
[Haven't played WoW in a long time though, maybe in Windows 10 and up you have an easier time alt-tabbing between heavy 3d apps.]
