Bad example. Guild Wars 2 caters to people whom do not have time because the entire game supports that concept. In thirty minutes you can achieve a lot and come away feeling satisfied. ARR is just another grind game - the only difference is they watered it down so simpletons can understand it.
The argument that higher level mobs take longer is not only regurgitating the 'game starts at 50' nonsense, but also supporting the bad mechanic of disproportioned scaling. Why should something be overtly harder at 50 than at 10?
