This has got to be one of the coolest thing Blizzard will be making as one of their official maps. I have always been a fan of DOTA, and with Blizzard releasing their very own version, with heroes and such, I can't be any happier. I am pretty sure that Blizzard will ensure that heroes will be fairly balanced, easy to play and learn, and like their other games, hard to master. I am not surprised, when there's actually full games released based on DOTA, Blizzard should have done this as well a looooong time ago.
