What about Dacia,
Theoretical, dacians were thracians. But Dacians were stronger and richer, they should start with Sarmiszegetusa and also make a city like Buridava, Piroboridava or anything with -dava cause dava means city in dacian as I remember.
Herodotus said that Dacians were the most brave and powerful from the many people of thracians. They should have more armour and no romphaias cause this were moesian. Some units like Tarabostes( heavy cavalry) , Drapanai(falxmen) , armoured falxmen, or Komati ( skirmishers)
