We're talking about trying to make the Sakae into more of a thorn in the side of Baktria and Parthia too. Having them in a corner (fewer trade partners), and in a place where there are fewer factions in general (the east) and with the engine bias against HA armies, plus in a place where cities are much much much more distant from each other than any other part of the map, it really makes it difficult to get them going. But we are still thinking about the problem, so I hope that gives some hope.
