Ok. Cool.There are random people in the Tower that rep different factions that you can join. You have to cop some of their Class Armor and wear it during Vanguard/Crucible Matches and instead of your bounties/rep going to the OG rank it goes to whatever faction you're in.
If you're not wearing the their gear it just goes to the regular stuff though...
I'm Dead Orbit Set too, but I stopped rockin' the cloak during Crucible Matches because I had realized that I already racked up a lot of rep already for Crucible. So instead of basically starting over and applying the rep/bounties for Dead Orbit I'm just going to grind it out without the cloak on.
I haven't really done as much Vanguard stuff so I put on the Dead Orbit cloak when I do coop stuff.
I'd say you have to look and see how far you got in the regular Vanguard/Crucible Ranking before applying your rep towards to any faction.
