I'm sure everyone is fine with Xur and The Speaker having their own currency. Why of the seven only two (vanguard) vendors accept something beside, pvp crucible marks? I hate, hate, destiny's pvp and it is annoying that the game is so lopsided toward pvp , when a lot of us want more pve. You could make the currency so it can be earned in pvp or pve ooooooorrrrr you could allow people to earn crucible marks while wearing faction cloaks, bonds or marks in pve like you do with reputation gains.
