Deleted the untouched Dragon's Breath that had been in my vault for months. Already had a maxed one on my Warlock (just to have one in the collection). Went with two friends to run the three Nightfalls and three Crota normals - this was back as level 32's with 331 weapons pre-HoW. I was given three more Dragon's Breath launchers - two from NF's and the third from Crota. It was that day I swore eternal hatred for RNG!
