Is there a limit to how many promotions you can give to an individual unit? I've been playing a game with a prolonged war. The AI kept hammering one of my cities, (that was nicely placed on a hill with a river around it and had full wall/castle upgrades). At first the promotions were coming like crazy, but it seemed to have maxed out at 4 per unit. Is there a solid 4 promotion per unit cap or is the experience needed just so much that a 5th promotion is impossibly difficult to get?
