I play with unlimited ammo. I also play as the Seleucids, so that makes it a feature against me. I believe in the logistics of war. You don't merely keep a handful of arrows, you have many. And in a battle, you normally constantly have runners bringing more ammo to the ranged units.

The javelin throwing is odd though. They shouldn't even have as many as they do in normal game. Is there a way to reduce ammo? We could make the javelin throwers have much less ammo (3-10), but do massive morale and health damage, along with armour peircing.
