After finding out that with the german version of the game the LTC mod has some sounds missing i started to use just the LTC Battle and Campaign AI with the vanilla game version and i must say it's way more realistic and more fun to play. There are more realistic alliances that hold longer and overall the AI seems much smarter. It's the only AI mod i've used so far but i'm very happy with it, so maybe you should give it a try:
