Thanks powerslave...I have added you and used your champion already!
@kris, I like your suggestion...or they can even show it in the main troopers screen, if anyone has used your champion in the past 24 hours before the daily reset. I would be happy just to have that information...doesn't matter to me when someone last logged in, as long as they use my champion daily. But I certainly see the value of it keeping track of usage for the past 3 days or so...will help the removal decision.
