The micromanagement task in StarCraft Broodwar (with TorchCraft) that has been used by a few people already in the past year to do some RL research has been tackled basically only with #units > 1, because getting a balanced 1v1 is possible only with certain combination of units, and it's indeed pointless otherwise.
Kiting is maybe a notable exception, but it is also restricted to a relatively small group of unit matchups.
