I said it before and I'll say it again, entire WWII is a too wide timespan. You can take it to an even greater extremes and create 1916 - 2005 areana where you can fight F16's with Fokker Eindeckers.
The MA HTC chose to make is a 1945 areana. The mid war planes are for veriety, the early war are a joke and probably ment to be used in CT/events.
I just can't see why the spit 14 is perked in this areana though.
