So with the release of The Taken King, Materials have been really easy to get, but not to use. Ghosts pointing out where they are, collecting some with each engram you receive on the planet Stacks way too fast. The Sword quest, gathering planet materials, another stack there. And the amount of materials per upgrade was reduced, so you go through them slower. Vaults now overflow with planet materials (and Etheric Light for you Prison of Elders players) Without anything to be spent on. So how about, a new exchange? 25 Planet Material for 50 Faction Rep 25 Planet Material for 250 Glimmer
