My idea for weapon parts is reduce the cost for infusion. 10 seems too high since we only get one per breaking down a gun so make it 5. Also allow us to buy like a pack of like 10 (same with armor materials) or something from a vendor for about 100 or 500 glimmer. Not much to spend that on. Than increase the amount you need to increase up to about 100 since they'll be easier to get. This way no one is in a drought and people with too much have a way to get rid of a lot in a short time.
