9-30 pure thrower.
Max PT, athletics, and WM.
Use throwing axe, javelins, or fransiscas.
I used a 6-33 thrower, but I couldn't fill up on points, so I switched to 9-30.
With fransiscas, you're pretty much an accurate machine gun and it's very fun + decent points, but not much power. The others are more damaging.
Playing recklessly on siege using up all your ammo with high athletics is quite fun. It might not be so viable in battle since you die in 1 hit unless you have some loomed cloth gear.
