These are some things that need to to be fixed:
1) The padded flat top helmet has -2 vision, when the normal flat top helmet and other padded helmets only have -1 vision
2) The coat of scales has more armour points and has smaller fatigue penalty then the heavy lamellar armour.
3) It’s not worth paying 1000 more crowns for scale armour compared to the lamellar harness. At least increase the scale armour to 250 armour points.
4) Could open mail helmets have only -1 vision and closed mail helmets have -2 vision?
