I don't intend to argue but to what GlazeyB said, I just had to laugh to be frankly honest.

No such thing as horrible RNG systems lol, do realize you have chances of getting majority exotics from ROC Strikes, Nightfalls, and some raids but you can't really get Crota Items from non ROC Strikes/VoG Raids. Don't reply to this for the love of god.
