With the release of the Age of Triumph old raids were made new and brand new raid gear was added as a bonus. Vault and Crota got new ghost shells. Oryx and Wrath got new sparrows. And all of them got new shaders. That said, these things seem to have a freakishly low drop rate. By extreme luck, I've managed to get the Vault and Wrath shaders; but nothing else has dropped (and trust me, I've tried to make them drop). Worse still, I've met several people that can't seem to get a single new drop. So... What's the deal? I'm not asking for hand outs; just a more balanced drop rate.
