So I've bought ice breaker and red death from xur. Proud to have spent the coins on them. Xur is meant as an equalizer for RNG. Simple as that. You can play for a day or 30 days... Doesn't mean you'll see a single exotic drop for you. So at the end of the day, congrats that you got lucky and got something to drop. While other people have run a couple weekly heroics and probably decrypted a few engrams to buy something they may never get any other way.
