Hi ToTameAGame, I understand where you are coming from. Competing in the arena without a prisoner is certainly a grueling challenge. However no one has to share their personal stats if they don't wish to.
Yes we know prisoner teams are and have always been the strongest out there. Not sure what seeing someone's defense stats for the week will do in terms of balancing out the playing field. As Silentknight noted the devs are sure to have something in place to counter prisoner teams and all we need is a bit of patience.
Just do as the rest of us and have a little patience. This is sure to be resolved soon enough (I hope).
