Er, I realize now I failed to address what seems to be your main point, and that is the balancing when one side is outnumbered. To be honest, I have no idea what to do with that.
Anybody else wanna take a crack at this?

Or... Does that situation rear it's head under the system we have now, anyways? I dunno.
Regarding introducing planes, I also don't have much input here. Perhaps introduce new planes two at a time?
Like I said earlier, I'm sure you guys have thought long and hard about all of these issues. It just seems a shame that while *every one of us* would like to see a two country map, nobody...*nobody* has developed it for any of us to even see what that would be actually like.
My wish is for you guys to disband the Knights, chop the map in half, and let us go at it for a week. Make us eat our words

. That way we'd finally know if it's truely workable or not. And I would bet that you guys are a little curious about it too.
In 2 years when this debate opens up again, we can say "No, tried it in the AH beta, didn't work"...OR..there will BE no debate as it worked so well that it would be what we were flying then anyways. I doubt though that you will lose any potential customers by giving this experiment a week during AH's beta period.
Maybe it's too expensive for you to implement at this point in AH's development. I just can't help feeling that a topic like this, which is so *fundamental* to our experience in AH, is one that if not addressed now in beta, will be too burdensome to ever address in the future.
