Food for Thought:
I think there is perhaps an exploitable niche market of AHII players tired of the farcical "war", the hordes, and yes, the unrealistic matchups of the same planes again and again in the MA. This is certainly the appeal of FSO and other Special Events to these players.
Yet these same player's vision of a "historical arena" might *not* be an arena where one gets the impression that the only approved behavior is to pick out the best "dueling plane" each team has, and then have it out in low altitude 1v1s.
Yet,to be fair, I realize that when you have ~4 or so players in an arena, that is about the only way to proceed.
