They'd obviously have spare quivers in their caravans but that can be hard to get to in the midst of battle.
I'd like to see something done about point blank shooting with oxbows and bows, issue is doing that promotes running away which most people hate. Regardless of the kiting issue I'd like see the zoom function switch on when your bow gets nocked or the crossbow is raised. Its quite an odd change but at the least it will make point blank shooting harder.
