I know Activision now owns Blizzard, but I don't know the extent to which these policies apply across other games. I know World of Warcraft has an active and thriving Linux user base still. I recommend checking https://appdb.winehq.org and https://protondb.org for reports on game compatibility.

Microsoft now owns both.

Actually apparently I'm wrong; looks like that's not finalized yet, and now the FTC is seeking to block it.

I think the gameplay and architecture of WoW means there isn't a huge market for "competitive advantage" cheats. Macros let you do most of that stuff yourself, and something that would auto-interrupt a particular spell is probably detrimental at high levels of play.

The only "cheats" I ever really saw WoW care about was botting, and that's probably easier to catch server-side than client-side anyways. Why monitor inputs when you can just see who's been fishing for the past 24 hours in a row?

no Diablo III and D2R work fine on wine, they don't have anti cheat like their shooters do

Oh for real? Nice, that's good to hear. Maybe worth checking into, then...
