I had played one game as Rome on v3.13 & playing one game as Mongols on v3.14. Here are couple of my observations. Ranged naval ships are OP against cities especially late game. This is magnified when AI leaves it's city ungarrisoned to attack your invading force. Then you can quickly bring your ships out of no where & bombard it. Then rush with a unit & tada, city captured. Order policy (iron curtain) which gives instant courthouses doesn't work as intended. Civs starting with a ship in start is too much of an advantage. You can explore at twice the speed & protect your fishing boats without any naval military investment. Rome having a naval UU makes little sense. Navy focus suits Carthage more. I would suggest some aqueduct replacement which provides wide bonus such as happiness. Keshiks don't get +1 move from their UA, nor do vanguard units. Keshiks have been kind of heavily nerfed. They get quick study but are statistically weak compared to Arabian Camel archers. There ranged attack should be increase to 22 or 23, while their melee strength could be reduced a bit. Cities now have ridiculous HP. While that is a great change as archers are kind of ineffective against cities & city battles become more strategic. But I think siege units also somewhat ill-perform against a well defend city. On the other hand ranged ships can make short work of cities. That is quite strange. My suggestion is to give siege units different promotions, 3 promotions for bonus against cities and fortified units & maybe 3 cover promotions. This would make siege units more suited for the siege combat. And I have a question regarding Mongol UA. When is the forced puppet trigger is supposed to happen? Do I need to have military presence to be able to demand a worker or it will happen even when I have ability do demand gold from them? That is for now. I'll post more of my observations later.
