LOL...I can always count on Karnak to attempt to shoot down any proposed planes other than late model cannon equipped fighters.
I think you have me confused with somebody else.
My first choice for an addition would be the Ki-43, which has a distinct lack of cannons and late war performance.
The Pe-8, on the other hand, is the type of idiocy that is requested by the "it must be uber" crowd, something that would be potent in the game but was a complete non-factor in the war.
(The cannon derision is also stupid. There aren't many machine gun only armed fighters once you get beyond the USAAF and USN.)
