I am finding irrational and unbalanced items in the armour tree. I should start by saying this mod, and all of your others, are pretty good. I agree for the most part that they are inline with the vanilla them.

I'm going to list one example.

Chestplate. middle layer - Yes, you would wear something under your chestplate, and you have the option of throwing something like a cloak or jacket over that.

Chainmail. skin layer, includes both arms and legs. - No, this is weird. You cannot wear chainmail on the skin layer. It goes over a shirt at the very least or simple padded armour. You cannot wear chainmail and a chestplate on top of that, you wear one or the other. Chainmail historically comes in a variety of styles including: head, torso only. neck. arms, skirt. And combinations of these. A full length chainmail outfit, as an alternative to plate which is also full length, is absurd.

I think chainmail should share a lot of properties with chestplate. both should be middle layer. Chestplate is torso and neck (perfect, I think). Chainmail should be torso and shoulders. Both are already near to the same mass, fine. Armour values and walking speed debuff need to be the balance for these. Possibly also time to don/doff. Chainmail is great against sharp and weak against blunt. Plate is a good all rounder, decent against sharp, blunt, and fire. However for game balance, balance them any way you like. My greatest issue here is that chain can't be worn along with plate - the same way we see a flak vest can be worn with a flak jacket.

I have plenty of others, I don't know if you are open to this type of feedback. I'll leave it there and hope for a reply.

Love your work, your whole team is pretty good. (are you looking for someone to correct grammar and description readability?)
