The AvA needs to keep it focus on history and balanced setups and not try to go to some version of an axis/allied split all planes arena. That sucked the worst.
I believe the focus of AvA is going to remain historical scenarios and scenarios with an historical flavor.
While there may be some aspects of the main arena style that could possibly be explored in the future, such as some type of map reset rotation. I do not believe a blanket all Axis vs all Allies planeset will ever be one of them.
