Can we fly on both sides? at seperate times of course
This is a good question. I am inclined to say no simply because each side will have a general strategy for the entire event. If people are allowed to swap sides, that strategy gets revealed and therefore tainted. But, I do not speak for the team. I think in the case of balancing, it would be overlooked. For example, if the Allies have 20 and Axis 10, switching to the Axis would likely be allowed.
I suggest flying either way!
