Got the Exotic Titan helm at 310 (Warlock perk helm) , sorry can't think of the name right now. It is closer to year 1 now , exotics and legendary items drop , just mixed in with new rewards. Relax people , I know some of the drops suck , this happened in year 1 as well. Your number didn't come up this week , keep trying , it will eventually. This coming from the guy who had over 800 hours into year 1 before my first Ghorn dropped.
