The sole satisfaction of hitting someone in the head with a jarid from afar is better than a 14.0 difficulty headshot with a bow. I've played countless hours of archery, but once I switch to throwing, it's like a whole new thing. To throw effectively you need to measure the projectile speed of the given throwing weapon and movement of the target. Start of with throwing dagger because it's easy and with lots of ammunition. Once you are able to headshot at 4.0 to 5.0 difficulty with daggers, say 150 prof, it's time to take out the axes.
1 throwing spear or jarid can dehorse a war horse with a headshot and enough Power throw, since if I'm not mistaken, thrown objects gets speed bonus as well.
