This is what Pyro said back in 2000 when the perk system was introduced:
Just to clear up a few things about this upcoming system.
It is not meant to be something that only elite pilots can get. That's not the point at all. If you fly like you do now, you will eventually accumulate enough points to get a perk plane. Most planes you will be able to fly all you want, so it's not like you'll end up gettting stuck with lousy planes if you don't have any points.
This system does a few things for us. First it allows us to introduce planes that we otherwise would not be able to include because they would upset play balance. It also helps balance out plane selection and brings more diversity since people can get more points by flying less capable planes. Last, it gives players a tangible reward for their efforts.
You do not need to be a top pilot or fly mega hours each week to achieve a perk. Flying more will let you achieve it in a shorter amount of real time, but you'll still have to spend the same amount of in-game time.
This is a purely a game system for the main arena. How a plane gets classified only has to do with how it affects the main arena, not with how it served historically.
This system will also be used in bombers and vehicles. A B-29 and Tiger II would be examples of what we could add as perks there.

The road to hell is paved with good intentions.
Perking the P-51, Spit16, Nikki and La-7 won't do anything to balance the arena. There will
always be a small number of planes that are more used than the rest. The most popular American fighter (biggest market and player base), the best runner, the best furballer, the best HO'er and the best ground attacker of the free plane set will
always dominate usage. If the P-51, Spit16, Nikki and La-7 are perked they will simply be replaced by the next best plane that does the same things well.
