You have to realise that arrows fly through the air at least twice as fast as stones (which are some of the faster throwing weapons). So even if I can throw quite accurately with them (even over long distances) it's still very hard to hit anything because you can just evade them easlily.
And yes they might hurt a bit when they hit you, but my stones are heirloomed and do massive blunt damage (13!!!).
It's not like I really understood your post or anything, just read something about a gogo person and stones.
