Maybe they could "encode" a "revolving door" that opens when 5 people are in the queue for a specific time. Then it opens and allows only those 5 in and adjusts the arena accordingly.
If one arena is full and another is not, then their plan is working. The ability to program an arena to resize itself based on the "gate or gatekeeper" on the fly would be cool. Unfortunately, logging in is very impersonal...it doesn't sort you by squad or country.
The split arenas were setup for the large uber squads that often overwhelmed sides and took unfair advantage of their numbers. Of course, we also have ENY to help there as well. Let's face it though, a number of us belong to a squad and came from a game that encouraged them and the comraderie.
We Cutthroats have been around since 1996 in Air Warrior and Aces High since 1999.
AH is penalizing them, IMO. This is what we have to work/play with now.
