I'm saying though, I was damn near at Crucible Rank 1 and a half before I joined Dead Orbit not knowing what exactly I was doing. So the matches I played with the DO cloak on and the bounties I got for while wearing that all could of been used for my Crucible Rank... that's what I mean a waste cause I was trying to get my Light up and that seems like the best way to go, with the Crucible Marks/Rep or Faction Rep depending on when you start.Just to give yall a heads up, if you get to rank 3 with any of the side factions (not sure about vanguard or crucible) you'll get a guaranteed legendary weapon. I tested this out and so did a friend. We got rank 3 with new monarchy and got one of the legendary weapons they let you chose from at the vendor in the mail.
Also getting a legendary/exotic armor or weapon that you don't use or want isn't a complete waste. Dismantling these items will give you valuable materials that you use to upgrade the exotic/legendary gear that you do end up using. So if im a warlock and I get a titan exotic chest, I could use the dismantled material to upgrade the exotic armor that I may already have. Same goes for legendary items.
I haven't gotten any armor outside of my class yet though, but I've been dismantling a ton of stuff because I don't have room and if the Light is lower than what I'm currently using I typically toss it in the bushes and deal with the other stats that I'm working with. Sapphire Wire is the easiest thing for me to get in this game, along with Weapon Parts
