RNG is RNG. Change your playing pattern and you'll get different drops. I never used to get hand canons. I do different things now and I got all 3 exotic ones in last few weeks. 2 fatebringers at once. As for duplicates, the more exotics you have the more likely you are to get something you already have. Explain how my friend got ice breaker right after turning 20 and never got a second since?
