So being honest, the only weapon I want the blueprint for is round robin. And it's the only one not dropping for me. But I'm barely playing right? Nah. I have every single weapon from that area unlocked, but you know how many round robins I have drop with red borders? Exactly 3. All of them from the mission. I still have weapons I haven't unlocked from the throne world because they just don't drop. Your system does allow for some players to literally never get something. I am confident that somewhere out there is a person who has played vault of glass three times a week every week since it was added to the game and still don't have a vex. You've reached the point in grinding where it authentically kills your ability to have fun with the game. What did you do this week in destiny? "ground the same event 300 times hoiping to get something to drop... " was it fun? "no" did you at least get what you were looking for? "no." For me it's round robin, for other players it's something else, please stop screwing with your players and add bad luck protection for events. This is ridiculous.
