Well then you need to play for another week or so. ALL THE GUNS ARE THE SAME. There is no grind. Once you do your weekly flashpoint and nightfall there is nothing to do except raid and grind a few challenges for higher light guns i.e.patrol. Raiding takes creating a coordinated team of 6 so most time is spent...doing nothing. People just troll around in patrol or strikes until they get bored of not getting anything but the same rolls on the same guns and quit.
