Well, I've only ever had one good nightfall, which gave me the Hawkmoon months ago. Always have had a mix of good and bad luck, for example I've grinded stupid amounts of Dead Orbit rep and still no revenant shader. But this week was one of the worst, I ran the nightfalls on my two characters and of course, shards and energy, and also ran Crota's end on both characters hoping for a helmet or black hammer, but he dropped me 2 shards for one character and 2 energy for the other. Worst week I've ever had, I deleted my low level Titan I was working on just to make way for a new Warlock and another raid attempt. Such heartbreak, very sad
