I think it would be very useful if you could request your Alliance to attack your Defense team. Such a match would be “recorded” such that you could watch the replay, move by move.
Such a feature wouldn’t be for any advantage or points, but to help a player improve their defense or try out a hero.
It would be helpful to see where Defense needs to be beefed up and allow senior members to help out with suggestions. “See what I did on move 16?” etc.
