If you want a good story on how someone got a gjallarhorn. Just ask smoggypluto. The rng is broken and Xûr just fixes a bit of it. A lot of day 1 players that run raids and nightfalls all the time and get nothing usefull out of them. While others had every exotic after 1 month or so. When it comes to rng there is only one thing to say. That we are all playing the same game but we aren't playing the same game.
