I like that idea, Oaty. It sounds like it would be easier for the programmers to implement than other restricitions. Anything that doesn't limit the number of them, even if it restricts where they can be belt, would still eventually allow a huge quantity into the game. Having modded my game to allow them to be built, I do see the AI Roman factions with them. They build a few, but they haven't made like Macedon and the light lancers. I've seen, at most, 2 in one stack.
