Yep, the old "random" ng right. Nope. Destiny has an increased chance to give you the same thing twice in a row. I've seen it with legendary and exotic weapons. Beating final raid bosses. Level up packages. Weapons received. Too many times to be coincidence. Today beat hard crota twice in a row = both got a helmet and shader, energies. The only time over beaten atheon twice in a row, both got an exotic. Several level packages in one day? Got several pulse rifles. Bought more than one exotic engram and turned them in at the same time= same item. Rerolled iron banner weapon 2 or 3 times really fast = almost exact same roll. Somewhere in there I started actively trying to not do the same thing within a short time frame. The one thing I can't seem to do anything about is receiving the same type and vendor of items. Before dlc it was invisible hand shotguns, machine guns and vanguard snipers. Now it's still vanguard snipers and machine guns. Still to this day I've only received 3 legendary rocket launchers, all solar. Had to roll ib launcher to get an arc. But I've gotten 4 truth, 2 jollyhorn and 2 dragon breath. Whatever.
