Well put Native.
My main character is a bec user, my two highest level alts are a sword n board and a dedicated thrower. Raising the requirements on low tier throwing would be a simple and effective fix.
The main issue with throwing is that it is too accessible for hybrids. Forcing PT on items like war darts to 4 would stave off most of the effects of this issue. When I am on my main, 1 v 1 against a thrower, I have little problem avoiding thrown missiles, even without a shield. When you fit multiple opponents in the mix, even if its still an even match up, avoiding projectiles becomes an issue. I think the damage, number of weapons per stack, and accuracy are all fine, but the accessibility of thrown weapons is the real problem.
Bear in mind: throwers may do more damage than a bow, but they severely lack the range, projectile speed (this is a huge disadvantage,) accuracy and ammo of a bow user. This means you need to be in the cluster-fuck of combat to make your few weapons count. The major draw-back of this is that you don't have a decent melee weapon if you're a dedicated thrower.
Ever tried to fight someone off with a javalin in melee? It ain't pretty. You can't run away either because you have very few points in agility/athletics.
Throwers are quite unique in c-RPG. Don't nerf them into oblivion because of cryers like this guy
Native has such a boner about throwing.
