Something can be said about balancing spears.
The damage is rather extreme compared to other trowing weapons, making it so that people will often spawn with 4 spears for easy one hit kills.
Trowing damage could be lower and more closer to damage from the stab, for when I stab something with my full weight and strenght behind it it will penatrate deeper then when I just trow it, giving the weapon back it's original purpose instead of turning it into an overpowered javalin.
I like that you can actually trow straight now, but (for example) maybe it can be modified so that bamboo spears are less accurate then jarids.
