Nothing wrong with a bit of Ancients action form time to time. With you be picking up some Sarmations/Scythians too?
The middle two blisters are Sarmatian light cavalry, since the Dacians apparently have no cavalry of their own. I'll probably add some cataphracts and horse archers later, but for now I'm keeping it pretty basic.
Nothing wrong with that, you'll.have your hands full putting together that lot.
