Only WoW, LoL and Dota are being translated through the Rosetta.

WoW itself is actually native Apple Silicon, but I believe the launcher uses Rosetta.

In my experience with gaming on Macs, even when there is a native Mac port of a particular game, the experience is inferior to Windows more often than not. Many of them don't do 4K properly, for example (you get everything rendered at half-res in fullscreen). Things like Cmd+Tab don't work reliably, either.
