I was looking at the rules about missile weapons and wondering why Thrown Weapons is a Martial skill? I understand that throwing axes and javelins may not be available to unskilled peasants. However, Brawling with daggers is still brawling. And what could be simpler for a peasant than throwing a rock.
It just doesn’t make sense to me that throwing a rock, or even using a sling, takes special combat training. Like wrestling and punching, most boys learn throwing before 10 years old.
