Again, HTC has never defined the word "imbalancing". You are defining it for them.
No, actually he's not, he's taking the logical step. We know two things for sure about the perking system: first, HTC has already perked an airplane because of its unbalancing affect on game play - the F4U1-C; second, we know that HTC does have a definition of what does and what does not consitute an unbalancing affect on game play, even though the details of that definition have not been made public. From what we know of the perking system and the spixteen's current perk status, the inference that it does not meet the requirements of HTC's definition is a fairly safe one to make. As I understand it, when the F4U1-C was introduced it became the dominant choice of ride in the arena by a large enough factor for it to affect the game. Hence the perk.
The Spit MkXVI isn't perked so the only information we can take from that is that HTC does not (yet) consider the MkXVI sufficiently unbalancing to perk it, performance-wise, useage-wise or otherwise.
The fact of the matter is that it is you who is trying to force a redefinition of what does and does not constitute grounds for perking an airplane in the game. And, doing so with the tricks of bush-league demagoguery. Twist or spin that any way you want and you'll still be pissing into wind. One would hope you have the sense to close your mouth before you drown in it.
