Just a thought Bruv...
"Mastering the whole planeset" is not something that "everyone" in AH aspires too.
Some folks, like Chudy here (after PMing with him) are more interested in finding some Historical immersion in the Main Arena chaos we call Aces High, then mastering planes we instinctively look at as "enemy" rides. I have never logged a nano second in anything other than German planes in nearly three years of game play ( MA ), and have no intension nor desire too, and will gladly put the Krupp steel up against the spitter of flames anytime.
Salute to all the squads, both US based and others. For me, I enjoy RAF squads that fly English planes, USAF that fly jugs and ponies, Red Airforce in la's and yaks, Marines in cigars, Navy in cats, etc...etc...
But I quess I'm old fashioned like that. Bottom line is there is no shortage of squadrons in Aces High. But there are only a few that embody the "only the proud, only the strong" motto that sets them apart from the masses.
Cheers.
