The entire vault of glass. People whom had done the raid significantly less than me had full raid sets before I got my first piece of raid gear. Imagine doing the raid 15 times and then your buddy comes in and does it his first time and gets two raid armor pieces. Hey, that's rng for you. It just really sucks sometimes, but it's also the biggest reason I stopped playing destiny when HoW came out. The taken King was an improvement so I'm glad I came back.
