One big choke point I have noticed of trying to level up another class is the lack of class specific upgrade materials. In order to get a health chunk one really has to grind quite a bit of strikes currently to decode engrams for materials. I over 3k plasteel plating, but I am hurting when it comes to essences and wires. I really want to try my new hunter more, but I slightly dread having to farm more engrams just for materials. Is it possible to add a feature to buy these materials out right for whatever currency, or exchange some of one material for another?
