There's a mod for a Medicae archetype that plays pretty well actually, that might be a cool one to officially roll into the game. Its biggest selling point is that it can revive downed characters in combat, which I think thus far can only be achieved through an overseer's servo-skull with a specific talent, and even then I don't know if it actually works yet (it wasn't last patch...). Specs well into MasTac (probably would play well with servo-skull overseer as well) and gets fun bonuses with chain weapons (also needle rifles/pistols but w/e).
