Not as much as you would think. In order to catch them, you need to bring down most of your defenses, as pro arrows breaks them when they hit. Still, if you really need some arrows, I usually find that stealing them is easier than catching them. A bit of stealth, and you are up one dead archer, a bow, and some arrows. Not for everyone, of course. I am sure Dantie would just walk up, getting shot the whole way. But then, he is rather slow.
