If it didn't see combat in WW2, it doesn't belong in the game (at least that is my oppinion).
Well I guess you know what I'm gonna say "add biplanes"

But really think about it, of we can have latewar ME262, and planes that hardly even saw combat why not biplanes? There were at least 175 Aces that flew biplanes during WW2, such as "Pattle" (not sure on his rank) with 15 victories in his Gloster Gladiator, and some (I think he was russian guy can't remember his name) with 14 victories.
Even the "Hawker Fury" (wich even I think is a little too outdated for AH, at least untill we get allot more early mono&biplanes) shot down atleast 4 bf109's and a bf110 during the war!
Sorry to get off subject:), the f8f May have a place in AH, once ALL WW2 planes are added, then they might expand the game, but untill then they should be working on WW2 planes I think.
