By design, Guaranteed YEAR ONE Exotics you don’t have if available to that character. I have not heard reports of them not working right in months.

Still not working.

The only Y1 exotic that I've been missing (besides MIDA, obviously) for months has been the Mechaneer's Tricksleeves, and every single week, my Hunter's gotten a weapon or something else that she already has.

It's poop.
