Problem is the devs did half the work. The AI pounces on almost all the emergencies and usually ends up "rectifying" them but.... it also fails to realise that half/all the world will pounce on it for capturing a city state... The AI has no concept of the extended consequences of picking fights with city states which in itself is a obvious game-breaking exploit especially in the early era's with low warmongering penalties. There was one city state which various AI's kept capturing after the first one broke its walls, each time an emergency, each time I joined... each time I took large chunks of cities as punishment/opportunism and together with the rest of the AI keeping the main enemy army busy and my annoyingly superior tactical ability crushed the opposing side's military capability. In each case the AI seemed mostly uninterested in capturing anything but the city state in question though the "aggressor" had no such qualms since he viewed it as just another war. The AI also fails to learn from it's mistakes and the one time I held myself back the one AI KEPT capturing and recapturing the same city state each time causing emergencies costly to itself....
The problem is that the AI only sees the military capability of the city state itself and fails to think beyond that.... basically by "fixing" emergencies the patch actually broke it at the same time. There is no way I could have conquered half the continent without majorly negative diplomatic warmongering penalties amongst the other AI's unless it was "global" wars where I had all the other neighbours keeping the bulk of the enemy army busy which in turn only served to weaken them before they brought an emergency upon THEMSELVES sometimes by conquering the very same city state that was JUST NOW liberated....
