Until recently, I've only been doing Vanguard and a little Crucible since I started. I randomly got Titan marks (engrams or crucible drops, can't remember) for DO and NM months ago. Decided it was time for a change so I just started ranking: - Dead Orbit on my main 32 Titan - New Monarchy on my second 32 Titan. - Will soon start FWC on my 31 Warlock I'm really just doing it to see what shaders or ships I might get. And to try something different from Vanguard. I'm tired of ranking it up and getting nothing. Plus the gear and weapons are kinda pointless for me right now (true for all factions really). I only use the marks to buy materials to upgrade weapons anymore. I've saved all my commendations just in case tho. I did, however, save up and get Saterinne Rapier from the Crucible vendor. Love that gun! I'm not expecting anything from the factions, it's just something different to do :) so we'll see. It'd be cool if they play a bigger role in some future expansion/story...
