The whole point of RNG is not getting what u want. The whole point is that if u play enough u have to get it right? Wrong no amount played will get u a specific exotic. U can play until destiny's 10 year plan is over and still not get the exotic although that's unlikely it's entirely possible. I have every exotic gun besides 2 elder cipher ones cause I haven't done Poe for 3 weeks and it's just all luck. I got every gun at least twice before I got my last exotic needed Gjallarhorn.
