Less restrictions is of course better, but I'm still not impressed without an actual Captain's Mode all-heroes draft. In addition inverse_pi's comments about all-heroes being vital because heroes have different roles to play, the draft is both an important part of the game and, I would think, one of the most difficult for an AI: it involves bluffing, mind games, online strategy adjustment in response to an opponent's actions, and awareness of the current meta. The draft isn't everything and it's possible that a sufficiently talented AI could always lose the draft and still win the game, but that would be a pretty boring outcome from the perspective of contributing to AI knowledge (just like it's possible, though unlikely in Dota, that sufficiently good micro could overwhelm any disadvantage in strategy and tacitcs if the AI can play at 2000 APM: it would "win", but only in a very boring sense)
