Bungie needs to put NPC's in the actual game. Imagine in crotas end if eris was following you the whole time and she actually handed you the rewards and commented on the situation instead of just giving vague comments back at the tower. The same for strike missions, when kade-6 or any of the vanguard introduce the mission why arnt they present at all? Just small things to show that other characters are present in destiny during gameplay instead of just cinematics and at the tower.
