I understand the wish for a forced balancing. But how should this work?

As an entrant to a server you are automatically switched to the outnumbered side or is it done when you are already flying and some on the other team leave and then I find myself in another plane on the other side?

What about 11:10 ratio (or 23:22 or 13:14, or ...)

What about 35:40? (that's no real outnumbering imho)

Could you force people to play on Russion side more in order to simulate the large numbers of Soviet planes on eastern front?

What I fear is that people will leave mostly if they cannot play on the side they like. We for instance are an RAF squadron and want to play on allied side. If we occasionally jump into blue crates it is because we want to.
