I think we should remove the FM2/F4F, the P40s, Ju88, early model 109's and Spitfires, Boston III, P47D11/25, and whatnot. Cuz, yaknow, they're outclassed in the LW arenas.
People won't fly new a/c no matter what is added. They'll keep along with their B24's, B17's, Lancasters, La7's, P51D's, Spit 8/16's, and N1K2J's.
