I hope you are doing well Erika and team!
As one of the "end-game" players, I was thinking about ways to make the game more playable during these non-season times. One idea that came to mind was additional challenges (running 2-3 per week) instead of just 1. It allows us to mess around with formations and still feel like we have something productive to do. I assume this would not be too difficult to do (but could be wrong).
In addition, it would be cool to add some new challenges that force particular crusaders into the formation (similar to events). I know this might pose an issue with new players but could be cool.
Over the last few weeks, I have just logged in once a day for offers and missions and then played in the challenges. Right now, I want to play but feel like I can't really play, kind of sucks.
