Since they made Cavs upgrade to Tanks, Mongolia has entered God Tier for warmongering. Nobody is even remotely close IMO. Here's why: 1. Keshiks can shoot and retreat, allowing casualty-free wars if you manage your positioning well. Very few other civs can war this way. 2. 5 movement units are great for scouting too. This helps your melee and siege units live longer. Furthermore, the swarming nature of Keshik attacks often serves to create openings for your melee/siege. 3. Because it's Deity, you fight a lot of units and strong cities, leading to massive leveling of all your units. This means supersoldiers. 4. The Logistics promotion, as well as all of the Accuracy/Barrage promotions, transfer over to Tanks and work. So after you war successfully with Keshiks, you can immediately steamroll the continent with super Tanks. My current game I grabbed Fountain of Youth (from a killed city-state) and went to warmongering. It definitely helps but is by no means necessary (just trade luxuries for luxuries to keep happy, and slow down your attack slightly. You'll be able to afford it with all the city-capture cash, and the healing bonus isn't that strong until Tanks because Keshiks don't take damage often). Here are my units, as I sweep the map: 4 Tanks with minimum Logistics, Accuracy I,II,III, March. These heal 4 per turn even in enemy territory if next to a Khan. Very overpowered. Note: 1 of these also has Shock I,II and two more have Shock I. That's roughly a 100% open terrain bonus for the former. HUGE. Another has Siege. 3 Tanks with minimum Logistics, Accuracy I,II,II. These were from my second, defensive war. I fully milked XP from bombarding and safely retreating from a powerful city. Note: 1 of these has Shock I now. 1 Mechanized Infantry with Shock I,II,II, March, Blitz, Siege. He hasn't seen much use since Tanks went into effect, but the 4 heal per turn in enemy territory (Khan + March + FoY) was fully abused as a Longswordsman/Rifleman. I love you Blitzy. 1 Artillery with Accuracy I,II,III. 1 Artillery with Accuracy I,II. I stopped using the former offensively about halfway through my first war, and the second was for defense. I also have made 5 Khans so far and captured Chichen Itza. Yeah. And all this in a game where I never once pushed a military tech. To sum it up: Keshiks -> supersoldiers -> rape ... this is the first Deity game where I'm seriously considering an overseas invasion in order to win by Domination, even though all overseas civs have their capitals. With 7 super Modern Armours though (and a slight tech lead), who can stop me? The only thing that stops me is unhappiness... but that can be rectified. By fire.
