Historical basis:
My throwing character wants something to use with the Railgun cybernetic I’m going to install one day 
I agree.
throwing chars need more high tier weapons besides forged weapons
Didnt they include a steel spear in the new build
Mebbe, I haven’t seen that yet. Whether or not I’d want to carry many of them around depends on its stats. The javelin’s superior to the knife spear as a throwing weapon because it takes up a bit less inventory, weighs less, and has a higher to hit value. Similar considerations make it my go-to throwing weapon of choice over other items that can deal much more damage when thrown, like machetes.
