By my calculations I'm at about 15 to 18 attempts, three more coming next week. In all that time I haven't seen Fatebringer drop once. Seen Praetorian Foil drop twice, once for a guy who had it already, and once for a guy who didn't even know what it was! Seen Praedyth's Timepiece drop twice, once for me (yay!) and once for the same guy who didn't know what that was either! It was his first hard raid! To be honest I'd rather have the Foil, I hope Bungie up the weightings for these weapons aftet the DLC is out.
