Well been playing 50+ hrs a week since I bought the game on December 7th 2014 and I have yet to get gjallahorn or black hammer I second the fact that I get multiples for instance I've received 10+ truths land beyonds I have 1 of each character don't know why but would like those weapons by the time I get them there will be something better oh and by the way once a exotic has dropped it will continue too
