No.
And no, i dont fly it either. I have *one* attack sortie in that plane and that one didnt end well at all.
If you perk the Spit16, you also need to perk the La7, the N1K, the Ki84, the Pony (and that would *never* happen) etc etc..... untill the only ones not perked are Hurri1 , Spit1, P40B and C202.
IMHO, the Spit16 is *not* overused at all. Yes you see it often, but hey, its a good fighter. But you also see Spit9s 8s, even 5s..... Id rather the Spit14 gets unperked, but thats another thread. And then the Spit16 isnt all that hard to shoot..... unless you happen across the wrong pilot in it, but thats not the planes fault, is it?
