I think I've only recieved three or so exotics across atleast three characters (atleast- since I've re-rolled some weeks) since start (or atleast since week 3 when I had three hars high enough to run it that many times). This week I recived another two legendary scout rifles and energies. I wouldnt go near NF if it hadnt been for the rep. At this point I'd rather have guaranteed exotic drops that we hd to roll for within the group. It would less of a slap in the face than seeing your fireteam mates get an exotic for like the 10th time in a row. I've stopped keeping track but the guy i usually duo with had a 18 times greater chance of getting an exotic than me a while back.
