I have almost 700 hours in this game and I've run VoG and Crota too many times to count...I have 3 32 characters...I have seen Gally drop 5 times, none of which were to me. It's annoying being the only one in my group that constantly gets Plan C and No Land Beyond. It's to a point that I don't think it's random at all. It's as if Bungie is a cruel step parent that just wants to make my life hell. Luckily, I have one (yes 1 after all my raids) Hunger of Crota to make up for it. I have actually contemplating stopping my game time and moving my efforts to another game because of this outwardly ridiculous drop rate...I may give it another couple weeks, we will see.
