Ever since guardian games the nightfall guns drop rates have severely been nerfed because i used to always get one after 5 or 7 runs on hero or legend now im lucky if after 12 master runs i get a nightfall gun and says warden of nothing is dropping and grinded all weekend and out of 30 or so legend and master nightfalls ive seen one duty bound thats all for nightfall guns and its never been like that its not bad rng its clearly another bug
