I haven't dug too deeply into the gear itself, but from my observations, the biggest difference between the factions (Dead Orbit, Future War Cult, New Monarchy) is the mix of attribute buffs. Future War Cult armor buffs Intellect and Discipline (boosts to super and grenade cooldown). Dead Orbit buffs Discipline and Strength (Grenades and Melee cooldown), and, you guessed it, New Monarchy buffs Intellect and Strength (Super and Melee cooldown). **Please correct me if I got these switched up** When selecting gear, the biggest difference within clan Legendary gear is buffs to different abilities and/or weapons. Like I said earlier, I haven't gone too in-depth looking at specific gear. I am now lvl 20 Warlock Sunslinger, and I have started earning rep for Dead Orbit...looking at switching to FWC though...
