I got Achlophage Symbiote (spelling) and Crest of Alpha Lupi, both of which I already have. I started to complain and then I stopped myself and realized, I already have most exotics. Of course the chances of me getting the couple of exotics I don't have is extremely rare statistically. Be thankful for what you have, there are some players that would have been extremely thrilled to get those two exotics I got in nightfalls this week.
