Many players probably have used this trick since the new patch came out. I just got an easy diplo win on Deity as Korea. Thought the following combo was quite overpowered in terms of gaining CS allies: 1. Freedom: Arsenal of Democracy: +15% Production towards Military Units. Gain 15 Influence from each Military Unit gift to City-States. 2. Commerce: Mercenary army: Allows the purchasing of Landsknechts 3. Commerce: Mercantilism: Purchasing items in Cities requires 25% less gold. 4: World Wonder: Big Ben: Purchasing items in Cities requires 15% less gold. You can achieve this combo easily on Deity, this means as soon as you have these 4 policies/tenet/wonder, you can gain 20 influence with any CS (not at war with you) every 3 turns with a mere 130 (buy and then gift a Landsknechts). this is more than 50% cheaper than buying influence with gold. A bit tedious to do but it is just insanely powerful. I had 15 CS allies in that game, completely dominated all WC and UN proposals and the CS were good military deterrents since they all have potent military. No Forbidden Palace since I was originally going for a cultural vic; after Globalization, i controlled 45 votes (needed 40 to win) with 5 diplomats in other Major civs. I think "Arsenal of Democracy" might need a nerf in the next patch. Or maybe they can allow the Mercenary units scale up in terms of power and costs with each new Era. I mean being able to buy a super cheap medieval unit in the Information Era, and gift it to CS to gain 20 influence just does not make sense.
