I suspected the same…RNG is most likely a complex algorithm taking into account the myriad of data that Bungie collects on each player. And I'm sure there is a small little piece that is random hence the whole RNG story. Bungie has to do something to keep us engaged until the next DLC. A few may get the exotic they've been craving, but most of us will not. It's liking betting against the house, a few will win but overall the house always wins. Now back to the grind….gotta get that jelly.
