This isn't actually MY worst loot drop, but it was pretty crappy for my teammates. I felt really bad after it, too. We were going to run the Nightfall for the week, but my internet decided to go down right before we started. So when it came back, they were at the end of the Nightfall and told me to join, i took about 5 shots at the boss and it was done. They got legendary gear and i got the Dragon's Breath exotic. Then we did the weekly right afterwards (where i actually did work) and i got a legendary engram.
