Hey, odd thought: What about making Ardat-Yakshi Infiltrators as opposed to Vanguards? It'd fill an interesting gap—there are no stealth-built biotics, and considering their in-universe history, they'd be the ones to do it. Cloak, Dominate, Lift Grenade. Also, since Dominate is worthless against electronics, maybe add alternate evolutions to balance, like a stock health sap effect, or the ability to detonate biotic combos? That would put it about on par with Sabotage in multiplayer, which, similarly, has an entire class of enemy against whom it's useles without the alternate effect.
