I wish there was a place that we could set up our team and, for lack of a better description, Raid ourselves. No loot needs to be involved. It would just be good to see how our line-ups respond to attacks.
I have also wished to be able to see my line-up in action. If there is not an arena that we can “attack” ourselves, it would be terrific to be able to watch a replay of Raids against our Defenses. It is always a mystery as to “how” our teams lose when all we see is a win or loss noted.
