I've done like 20+ nightfalls so far this week. I've farmed it in solo speed run, with team, with buff only and debuff only, with high scores (70k+) and low scores. No drop at all. Oh and to the 20 nights done this week you should add the more or less 40 other runs done during previous weeks. Is this goddamn gun drop bugged again? Does the score (or the moltiplicator) actually affect the drop chance? Any proof ?
