That should help, although I still think something is wonky with the AI's selection of units for an army. I just had a battle where the French invaded my territory with a single stack containing 10 catapult units and 7 crossbow units... and nothing else. Yah, just the thing to go up against my cavalry-intensive armies. At least the higher cost should reduce that kind of nonsense, and I don't think it will affect the player that much. My use of artillery is constrained more by movement speed than cost.

The other stuff looks good. I might try this for my next campaign (Turks, probably).
