We JUST had a player quit the forum in frustration at not being able to shape a better narrative through forum activity:
What makes you think you can do better?
Blizzard does do some stuff in answer to fan response–for example, they clearly had no plans for a new home for the Night Elves, but they mentioned that they’re considering possibilities now. However, I don’t think this is the place they pay attention to when it comes to fan dialogue. Twitter seems to be more where it’s at.
