Purchasable Challenges

Something that promotes FOMO is the Capstone challenges being unavailable the next week.
The Challenge and Reward should be permanent after unlocking said challenge.

If you miss the challenge 1 week, you shouldn’t be punished for it. Nor should you be able to just buy the reward straight up, it ruins the point of Capstone as a whole.

How do 343 fix this, be able to buy the challenges. They could sell them for a 1,000 or 1,500 credits each. They could also sell an extra weekly slot, to speed up getting the capstone, every week for like 200 or 500 credits each time.
