I have found myself in a position where I have over 700 Plasteel, but 0 Weapon Parts, and over 200 Helium Coils and Spinmetal Leaves, but 0 Relic Iron. Can you implement a way to trade these materials for other materials of the same category? Armor Parts - Weapon Parts Relic Iron - Spinmetal Leaves - Helium Coils - Spirit Bloom You currently have the option to trade in Ascendant Materials, etc. but not these relevant materials listed above. Another feature that is not as necessary in my opinion would be to sell or purchase these Materials for Glimmer. Edit: You know what, it occurred to me that since they are introducing trading in the future (The Taken King) this probably won't be necessary. You might be able to just trade or buy these mats on the market.
