Please do 5 invigorations a week.

This might fall on deaf ears, but I am passionate. I see the invigoration system as so much incentive to get all frames and farm resources each week, but not like how it currently is.

5 invigorations a week and doing 4 gets the mutation is maximum incentive to use it every single week as much as possible. It's a real motivator then. Test it out and see how much more activity there is. I am willing to bet it increases the frames being bought and player activity in farming missions.
