More spartan ops mission or challenges?

I absolutely love spartan ops, but I feel like the missions get boring after the second day they are released, maybe add more missions for each week or maybe there should be more weekly challenges for that weeks missions or make the challenges longer or harder to get. because this week on episode 5 chapter 1, i got all three weekly challenges done before the mission was over, kinda lame. any one else have any ideas or input on this?
