About weps: I saw that the Vault had changed, and I'd like to know how? Also, upgrading weps, you said we can "Sacrifice" a Legendary to upgrade a Year one legendary...will it be Viable for TTK, and usable? Or upgraded a small amount? It also seems we don't need our exotics in the vault anymore? Light and Ghosts: What are the main light function? Ghosts are fascinating to me, so does every faction and vendor have a unique shell of their own? Please consider these for the Stream, Cozmo...
