A Domadore Enforcer/Henchman would be very cool (although the thought of painting it makes me just as sad as the thought of painting the minion versions. Or painting in general!)
I'm not sure about the Thrall though. There's not much personality in an enslaved beatstick. A named Handler who is particularly skilled at controlling Thralls though. That I would like to see.
Val, Anna, Toshiro, and manos are on top. After that, nada. You don't take Datsuba OOK and shes good in Kirai for sure. Sloth is super situational.
Also Outcast just seem like they do better against ressers, and I think it has a lot to do with the ranged attacks.
