As the ruler of your kingdom you should also be able to give orders to your clans. Like having them stationed in a region, defending/attacking a city. Now they just run around and you just hope you have some friendlies on the other side of the map if someone declare war on you. If not you have to drop everything and run across the map... They should draw inspiration from Total War to be honest. Peacetime would be more fun if you had to manage food production, unrest etc and not just drop 200K in the city and queue all builds and leave it..
