Graphics don't matter in an MMO, in fact a cleverer use of graphics can increase an MMOs userbase by lowering the system requirements allowing more people to run the game. Here's an idea why not wait and see how it plays before you judge a game? An MMO with a good story sounds like a great idea to me, it will be great if it makes you character feel important in that world instead of a clone of the next player doing the same meaningless fetch quest as the player next to you.
