Pathfinding needs some work, when moving large groups of units the ones in the back tend to move away from the ones in the front rather than trailing behind.
Other than that I'm confused about the design.
You start in your base and the available units are predetermined, you have little choice over the composition and you get a full army in a couple of minutes, then move your army around and chip away at nearby enemy concentrations but it seems like even a full army isn't enough to make significant progress before it gets wiped.
So you kinda want to bring your king to fights, but also he needs to be back at the coven to remass your army quicker? Are you supposed to wait for a bunch of support buildings to buff up your coven before being able to do significant progress?
Other than fighting whatever's closest with your mass, you can micro your envoy a little bit to scout and pickup trinkets but that's it.
I don't get this game, I have the feeling I'm playing it wrong or something because it feels like all you do is mass a weak army, attack-move towards the closest enemies and repeat after they all die.
