We can currently obtain 6 PvE weekly bounties per week - 3 from Petra and 3 from Variks. Unfortunately Petra's bounties only give queens rep which is basically useless at the moment. At least Variks gives us PoE rep which can give some good weapons. However I totally get the desire for more sources of Vanguard rep, especially as the Vanguard bounties at the moment are somewhat trash. They aren't challenging, they don't give much rep, and they get completed almost as an accident most weeks. I think an additional bounty set, from the Vanguard directly would be a great way to focus play into specific story missions or strikes on heroic difficulty. The harder the bounties, the better. It would almost provide mini PvE challenge modes. "Defeat 3 Taken Zealots without dying" "Complete 3 Heroic Strikes without dying" "Achieve gold rating on public events on 3 different days this week" "make 300 headshots" So on...
