The 16 has a lot more deaths, and lower K/D, because the CHog was and remains a vulcher. Short flight off a CV, bunch of vulch runs, retreat to the puffy ack, and land.
I'm not sure why you keep saying we'll only have La7s. La7 kills, and K/D, are up, way up, since the 16 was introduced. This can't mean that all the La7 pilots upgraded to spits, and that perking the spit will mean another 40000 La7s. This is just your attempt at panic-mongering to attempt to prevent what must obviously be done.
You keep saying the Spit isn't good at anything. If it's such a rotten plane, why does anyone fly it? It's not well armed, it's slow, it turns poorly, blah blah blah. BS. 44,000 kills. More than any other plane. Perk it. Sick and tired of seeing nothing but free latewar uberspits hording anything in the air.
