i dun wanne discredit sirian, but i think he cant consider all strategical aspects of a map and more important a human may accidently give some team not obviouse but vast edges. which leads me to the conclusion, that a somehow randomized map, that is manualy balanced, may give fairer chances, than a totaly styled map. additionally imo a somehow randomized map brings more interesting or difficult strategical circumstances leading to trickier solutions providing more fun.
