Isn't chainmail armor more expensive than iron armor with these recipes?
By default, crafting chainmail armor directly from chains costs more iron than standard iron armor.
To fix this balance, download Craft More Chains, a mod/datapack that gives you 2 chains from the chain recipe instead of 1. This makes chainmail armor cheaper than iron armor.
