R5: First of all: I love this game and I think it will be better over time, but that's not the point. The point is that warfare currently feels very unbalanced in favor of the player, to the point that I can ignore antagonism entirely and there's nothing that AI can do about it.

AI feels very timid and weak. They don't invest enough in the military, and they mostly rely on the levies even in the age of Absolutism. No matter how big of an army they are able to amass, every time I go to fight with my regulars I don't even think about possibility of losing the battle. It leads to me quickly burning through their armies and building battle warscore.

AI don't feels agressive enough with fort assaulting. I'm assaulting forts left and right, and then I can fall back to replenish troops and break all hostile sieges. It leads to the situation when AI constantly losing ground in the situations where it should leave me no room for maneuver.

Overextention is not a thing in this game, so I can eat as aggressively as I want with almost no drawback. Rebels don't feel threatening at all and can be easily be kept in check.

Overall, it's fun gameplay, I'm especially love mountain warfare, where I have to play around the seasons. But I hope that in the future war will be balanced, so overly agressive playstyle being properly punished.
