dotard think blizzard made 'the game' and some think it is an MMO, and later blizz would place updates here and there to screw their own business, where it was just a custom map build by Eul based on AOS, improvised by guinsoo and currently maintained by icefrog that wasted so much teen's rage on the game instead of spending time with chicks.

oh, and blizz don't even care the update patch screw the custom map up side down for the sake of normal strategy game.
