You could take the WoW out of those statements and fill in poker, cigarettes or alcohol in stead. If you have the disposition to get addicted, then you have to find out how to fight that.
You have to "just" have the mental strength control whatever it is you are using. You can be a light smoker and quit at ease, or be heavy smoker who never gets to quit. You can have a beer or two at parties, or you can be an alcoholic. You can treat games as what they are - a fun passtime - or you can become addicted to gaming.
Same shit, different wrapping.
