Why does it need to? The world doesn't evolve around Carl. Maybe you should play Rift or something instead, you can do a 5 minute Warfront, or blaze through an instanced dungeon and not even bother wasting precious seconds talking to the other people.
I'm sure there could be something that is enjoyable in small chunks, but really, not everything has to be for everyone. Maybe it's time some of you sat one out for a change, and let the people who don't need instant gratification have a game for once. The problem is, the two types of game are not really compatible. And the problem with the I NEED FUN NAOWW! people is that you log in for 17 minutes, realize that your XP has hardly moved, and complain that it's too slow. And so does the other 800,000 WoW refugees. So the developer speeds the XP rate up and removes the corpse runs and all the stuff that takes time. And the result is that you people blast through the levels and then quit anyway because you are bored. And the people who liked the game all along, they still want to play, but now they have to play the turd of a game that is left after you locusts have fed off it and all moved on to the next flash in the pan 15 minutes of glory instant gratification game.
