I love a lot of the concepts, but I feel at the level of complexity the combat has; it may very well be easier to get a war or skirmish group together. Or rather, at that level of complexity I feel both sides should be playing to win. 

Basically I wish it would go harder into being an asymmetric skirmish game, with the DM side having progression tied to player victories. That way both sides get to progress at the same time.
