So your telling that magically out of 12 tries, he managed not repeat 1 out of 24 exotic weapons? Minus the Vex... 23, minus the Hawkmoon and Monte Carlo, 21. He hasn't sold any exotics that offered from Bounties, Thorn, Invective, Bad Juju, Fate of all Fools, Pocket Infinity, and Super Good Advice....14. 12 weeks and only 14 Exotic weapons can be sold, and not 1 has repeated. I don't think you understand how RNG works.
