Does anyone know how are Arena opponent teams set up? Is this based on player teams with unfinished games in Arena? Or is it based on past teams set up regardless of whether the Arena run has been complete? I have started an Arena run which I have yet to complete. Does this mean that until I complete the Arena run, the team I have set up will consistently be in the list of player opponent teams? ( Got DB; started Arena to see what the fuss was all about; quickly got bored; left team there).
