RTHolmes,
It wasn't very clear on my part but it's supposed to be an opt in/out kind of thing. For example, the squad CO gets in the tower and gets a message that the other arena could use more players for balance. He then decides to move to the other arena, now the players in his squad (Only when they get to the tower) get a message, "Your CO has moved to another arena, would you like to move with him?" That player then can choose yes or no depending on what he wants to do.
The goal of my ideas was to still allow everyone to play when/where/how they want, but to give HTC some tools that would allow players to help arena balance.
