I gave it a "slightly better", although I really did have my problems with that.
Still, the AI is happily throwing archer-type units at your melee front.
Defensive fire from redlined cities is concentrated upon full health ranged weapons, while "yellowed" enemy melee troops are near.
Coordination between units is still unknown.
It does very slightly better on city defense, though.
In total, I would say the skills have gone up from a 35 to a 39 (in a range of 1 - 100, with 100 being the best).
Whoever faces a challenge when fighting the AI (supposed comparable units/number of units in a given theatre) has some major problems with fighting.
