I'm fine with all of it but the country switching business. It's not the chess piece thing, I've flown for all countries, I just think you build up a comaradarie with your friends and ruining all that just to keep numbers even is overkill. Not to even mention the effect it has on squads, as has been aptly mentioned.
I'd rather fly a 51B or a 38G than have to switch and fly with a bunch of guys I don't know, and wind up killing guys I do know, or worse, getting killed by them.
Not like I have a choice, but that's my opinion.
