My idea for armor balance: First, make all stat bonuses a craftable mod instead of inherant to the armor. Like make armor plating give a Vit bonus, weight reduction give an Encumbrance bonus, etc.
Second, make all pre-epic armors have identical weight and defense, including “clothes” and Religious armors, as every other set in the same weight class. Exceptional and Flawless boosting armor and durability as normal. Give these one slot for mods.
Do the same for exile epic and lvl 60 world-found recipe armor, and add epic versions of all pre-60 outfits. Give these two mod slots.
Finally, all boss room armors should have the same stats as the epics- but these carry a third mod slot to make them worth the effort of getting at the recipes
