Nope. Buy a class specific piece from the dead orbit faction vendor (like a warlock bond), equip it, and play like usual. The reputation you earn that typically goes to vanguard, goes to that faction. After ranking up past level one (I think) you will start getting packages from that faction instead of the vanguard. You have a chance at getting faction specific shaders.

Ahh nice. Might do that. Going to try and get a lot of Vanguard points for HOW weapons. But might have time to try that. Thanks.
