I agree. The AI is broken. It aint able to fight, just shuffles units. Doesn't upgrade units, doesn't pillage when able, doesn't protect settlers/builders, build wrong type of units. In my last emperor game the other civ still have tons of warriors in mid game and Greece kept making catapults to defend Athen under siege. In another game, my two neighboring civs both DOW me, but didnt attack. I soon realised they actually didnt have any military left, at that time, after both had been getting killed by a single barb camp spawning cav units. This need some serious patching, it baffles me that this wasn't noticed in testing.
