Here is an idea for your your show:
Talk about requirements of certain commendations such as flawless requirements.
Ex:
What happens if a player leaves the mission area?
What about if someone joins in the middle of the mission?
No need to be guessing, this should be a relatively easy for you guys to do.
Talk about the mechanics and techniques of certain parts of the game, such as how multiple healing stations work.
I believe that topics like this would keep us interested in the SOTG
