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?
