Hey guys! 
I just finished an immortal game as the Inca, and decided I'd try playing the game with a team mate, I'd only ever done it for multiplayer (on a side note, teams make science go ridiculously fast).
Naturally, I was matched with Ethiopia who proceeded to fail about as hard as a bad AI fails. He managed to get 3 wonders, when wonder spamming, and two of them were because literally no-one else built it. It was fine though, I held up the team and we did end up winning. It was just incredibly infuriating with a weak AI team member; it may be better with a strong one. I don't know if they plan on working on this, but they really should. It doesn't just affect human and AI teams (although this is when it is most notable), but also AI teams.
The game was a standard Pangea, 2v2v2. Inca and Ethiopia vs Austria and Carthage vs Siam and Denmark. Random teams gives a bit of a weird combo. Problem was, throughout the game any diplomacy any of the AI made was automatically carried over to every other AI/me. An example of this is Austria became a powerhouse mid-game, and bordered Ethiopia, so they declared war. They would never have declared on me (having both a size, production, military and technology lead on her), but 'unintentionally' did. This dragged Carthage into a war with me, and I proceeded to crush her largest production city and take it for my own, and gave me artillery/bomber/nuke range right to Carthage's capital. Carthage would definitely have never declared on me. Additionally for early game Siam was rank 1 by some margin, but surrounded by both Austria and Carthage. The Danes at that time were more powerful than Austria, and so declared war on Austria, dragging Siam into a war with both Carthage and Austria, losing them two of their 4 cities. Again, Siam would never have declared that war. This should really be changed.
TL;DR:
AI don't take into account their team mates when declaring war, leading to many situations where the AI/human team mates can get heavily damaged when they wouldn't have declared the war normally. This should be changed so both AI must judge the war to be beneficial before declaring, or the majority in cases of > 2 team members. Same thing goes for if a human is there.
P.S. Should you get a diplomatic penalty for something you have no choice over? My example here was me trading with Carthage and Austria, had DoF'd both of them, then Ethiopia DoFs Denmark, accepts a bribe to DoW on Carthage/Austria and forever ruins my relations. Probably should be changed as well, hey?
