AI get´s "free" troops when they respawn/creates a new party. I think this "kickstarting" needs to come from somewhere and I think the number is based on what fiefs they have ETC but I don't think it affects the fiefs which I think it should! Let it add a malus to prosperity and/or militia count or even a direct hit to it. After a few "partyspawns" they start to take severe economic damage and stops to respawn or slows it down. This way a faction maintaines the ability survive first few defeats and still resist but it has a turning point - now they will not be able to muster a new army for a while.
In addition, it could cost them some Influence. There´s another pool that can be drained that slowly drags down the resistance and makes wars not feel eternal.
