Bungie please allow us to be able to purchase the class specific upgrade materials. Plasteel Plating, Sapphire Wire, and Hadronic Essence. This is very simple and the only thing holding me back from equipping my new gear obtained in raid and nightfalls. Make it for vanguard or crucible market or even strange coins but I would prefer it to be exactly like how the planetary materials are now. Please add this Bungie.
