I think you're mainly viewing WoW from the PvE (player-vs-environment) perspective. In PvP (player-vs-player), there is a system much like the one present in Starcraft II (except that there are no leagues, only ratings).
In a game like Quake you are only as good as your Rail-gun aim it's pure skills.
If you spend years playing Quake/Starcraft, you will be good at it.
The advantages from these kind of games in combatting addiction is that they are hard to become good at
I don't see how that combats addiction. I played competitive Counter-Strike Source for some time, and the main thing that kept me going was just that feeling of competition, and wanting to become better.
WoW's addiction factor is different. It's more like "if I don't do X on day Y, I get behind other people" where in games like Quake/Starcraft, that just doesn't exist.
