bounties

I've read that after rank 3 you get a reward for each subsequent rank you achieve like you do with the cryptarch, so an engram and some glimmer probably. After I hit vanguard rank 2 I sided with Dead Orbit and am just about to hit rank 2 with them however I only realised last week that the 3 different factions seem to specialise in what stats their armour has, so Dead Orbit has armour with discipline and strength, Future War Cult has discipline and intellect, and New Monarchy has intellect and strength. So I guess depending on which cooldowns you want to reduce (super ability, grenade, melee) will determine which faction to side with. @TheTLady, I wouldn't mind teaming up for some of the "Do this mission with heroic modifer active" type bounties. They don't seem worth the effort of doing them by myself for 100 vanguard rep and some XP but with a fireteam you could probably fly through most of them.
