you could say the same thing about Doom in the mid 90's as just because one game is able to do something well for the first time and may be considered an eternal classic, doesn't mean no one can do any better. I mean if Doom clones were ignored for being inferior to the original Doom then we would never have gotten Half Life and the entire FPS genre.
Props to Blizzard as it has shown the way but this is a very immature genre and is soon to develop into something really special.
