Ive got a solution, at least for archers.
Make Powerdraw 4strength per level, not 3.And decrease the requirements of each bow by 1.
This will heal ranged fever for archers.
You will need 21/18 Builds to use 2slot bows, meaning you will be easier to catch for infantry.
machinegun Hornbowusers wont be as viable as before and stuff.
