What if instead having to come up with entirely intricrate abilities for Exotic Armor catalysts, why not just give the option to add an additional perk slot to it for free*, and instead of players farming for specific armor catalysts, they farm for a new consumable called "Armor Catalyst", crazy right? It's a one-time use consumable that enables the additional perk slot for Exotic Armor. *like a maximum of 3 energy or whatever its called so its not super crazy.
