(Keep in mind throughout this post that I utilized the Aggressive AI option.)
Kay, I've played a bit with the improved AI of this mod now, and it seems pretty potent. However, the way it's done really turns me off. In fact, it turns me off so much I really don't want to play the mod with my current options. Which we'll get back to at the end of the post.
See, the AI makes great decisions now. I have played a game as Greeks where I was isolated with the Vikings on a continent. I conquered the Vikings as soon as I could and started fast-teching (Because if I didn't, tech trading would get me so far behind I would have no chance to win this game). When I then meet the outer continents of Ethiopia (That also ended up on a lone island) and the Old World which was basically Sumeria's dominion, it took ten turns before Ethiopia whipped up a naval Galleon landing to exploit my bad position.
However, here's my problem with the AI: While it is much better at punishing my weak points and amassing a fast naval landing to hurt me as much as possible, for Zara himself, the whole naval landing was pointless. All he did was to amass his whole army and throw it into one of my very wealthy coastal cities and raze it instantly. Then his army died when I encroached it - I did manage to build a few cuiraseers at that point - but really, the few games I've played, the AI really seems to like doing this; throw his whole army suicidally into a wealthy city of mine and raze it. Which leads absolutely nowhere for the AI. In fact, the whole effect of Zara's war was to piss me off and make me feel bad while the actual lead - Gilgamesh - was free to lead continually. I even had a huge production surplus compared to Zara in addition to the military power. Zara had no chance to win whatsoever.
I feel that warfare should be a tool for a nation to assume control of new resources and expand power. Zara ruined his own military standing to remove a coastal city. I really don't have anything against losing cities, but with this mod everyone's warfare strategy seems to be pointless in the Montezuma degree - just randomly declare war against someone and suicide everything while ruining that someone's economy. Wat. The beginning of the game against Ragnar was spent defending my city when
he DoWed
me and sent 5 archers into my 5 phalanxes. Again, wat.
The thing is that I could easily spend a few hundred years conquering Zara, but if I know the AI in this mod (...), Gilgamesh & Friends will just DoW me as soon as I make a proper landing into Ethiopia, leading to them conquering me rather than Zara, in the end.
I therefore have some thoughts on the AI design:
1) Tactically, in regards to handling singular battles, this mod does it great.
2) Strategically, well, it doesn't. The AIs seem to randomly DoW only to remove cities. Zara even did it while on pleased, which haven't happened to me before...
3) It
feels like the AI doesn't really play to win here.

Rather, it reminds me of old Civ2 days where all the AI did was to play as a cooperative bumper for your war juggernaut. I personally prefer the newer game design idea where the AI has self-interest and acts as if it was another player with its own interests.
4) I think this whole deal is a consequence of the Aggressive AI thing, though. I usually have it on since it's kind of more true to real world history if nations fight more than they do in regular civ, but I have a jist the option really isn't suitable with K-Mod. Which is my personal explanation of Zara's completely unfun and douchy behavior; aggressive AI. I am not going to have it on when I play it again. The AIs merely seem to gang up on the player which will make any lucky AI win, not one AI in particular because of imperial aspirations, but rather because it's a player and he has a city open to raze.
EDIT: Any kjind of explanation for this behavior would, of course, be very welcome.
