KARNAK cool list, but I personaly dont think we should perk the Me 163 due too it lack of fuel, and it is not an Uber plane. The Me 163 could see some use in Airfield scrambling vs Bombers. But due too its limited fuel, it will most likely not be that effectiv vs figthers. And flying the Me 163 is for crazy pilots only (and they seldom have alot of Perk point, lol like me

)
And if Spit 14 should be perked, then the Fw190 Dora should also be perked. I think both the Dora and the Spit 14 reached frontline service abt the same time.
