So I thinks I might have an idea of how to get a faction shader from New Monarchy, Dead Orbit, or FWC. My Titan already got the Revenant shader but I believed it was random. My hunter is in New Monarchy and today I got Nefertiti AK at Rank 12. I don't know if this is true but this is what I did. I was joking around and before I picked up my New Monarchy package, I put on my cloak and Legendary New Monarchy Emblem and when I got my package, Nefertiti was in it. When I got my Revenant shader from Dead Orbit, I had a legendary dead orbit emblem and mark as I grabbed my package. I know more than likely everything is just random but who knows? If anyone else has had a coincidence like this, post here!
