I'd play LoL if one player per team could play as the minions...

DotA has a few heroes you might be interested in! Chen and Enchantress have the ability to take control of jungle creeps and use their abilities. Enigma, Broodmother, Visage, and, to a lesser degree, Lycan, Beastmaster, and Brewmaster have abilities which summon multiple controllable units. Illusion-based heroes like Naga Siren, Terrorblade, and Phantom Lancer which can create temporary copies of themselves. And, of course, there's Meepo.
