Does the AI expand too much?

I will over time try to make AI more competent at defending minors it has an interest in defending (hopefully also receiving the diplomatic toolbox to do so, because right now it's really not that easy to keep minors alive even for a player due to 1 dip slot cost/alliance and even guarantee.)

Like previous posters already noted the game simply doesn't model internal entities that could cause large empires to fall apart to any great extent, and your EU4 country is for most purposes a well coordinated monolithic entity.

The problem is that there's really no difficulty for the human player to match that, and if the AI doesn't do it will inevitably be easy mode. This by the way makes me think I could probably seriously reduce blobbing on lower game difficulties (Easy for a start) without this constraint in mind.
