I'm playing a Diplo game as Hungary and I'm getting into a lot of protectorate wars. Something I noticed after seeing the AI conquer several City-States is that once they conquer it, the AI just pat itself in the back, say "good job me" and move all units away. It seems to set conquering the city as a goal then it just go back home, completely ignoring any threat to said city. That mean you can just let the AI conquer the city-state, then watch all its units moving away before you move in and liberate it.

To solve this, I think the AI should at least assign a garrison after conquering a city. Maybe have a cooldown before it send the attack units to god knows where, so they stay around for a few turns protecting the city. Basically the AI should have basic notion that a city that was just conquered is vulnerable, mostly if it sees my army approaching or just lurking around.

Speaking of vulnerability, City-States that where liberated are too vulnerable, which means the AI is likely to declare war on any CS you liberate right after you do it. It have no military units, no walls, it's just sitting there like an easy target. You need to babysit any CS you liberate and pray for the crab god that no allies will declare war on it, since you can't do anything other than surround the city with units to prevent an ally from conquering the CS. City-states need to get a little help right after they are liberated. A free unit, free walls, maybe both.

Another thing a bit unrelated that I noticed is that the AI seems to be worse at building walls since the patch. The AI behavior in combat is improved, garrisoned units are attacking now, which is great but there's so much cities that are there, without any walls, just waiting to be taken without any effort. The AI used to rush walls when it was attacked, it doesn't seem to be doing that anymore.

Yeah I've seen this as well.

We were discussing this in the patch thread as well, definitely seems to be the case. Pyramids are very easy to get now, so I think the AI just isn't prioritizing masonry anymore.
 
I think a similar thing happens when you capture an AI city as well. It's like, even though the AI may have a hefty force that could be used to actually take the city back, they will almost always go "nope" and either pull back or just... break. Like it seems to lose all concept of what is doing and just flail around and be killed.

When I declare peace with the AI, I wind up declaring peace with any CS's I was at war with for 10 turns. Sure that's not the case for the AI?

I can tell you that you can denounce and declare a Protectorate War immediately with waiting 5 turns. If you just liberated a CS, it's your suzerain.
