tinkles,
I think it has been pretty much explained that most people dont fly planes due to eny but because they have fun in it. most players dont play for rank at all.
as an example, I'll say me. I love playing the ponyd, not because it is fast, or because it as 6 .50 mg's but because I grew up watching movies about how the pony was the best airplane in ww2, blah, blah, blah.
I dont care if I rank #1 or 10,000 in it. I just love flying it. my other airplanes are the il2 as a tank buster and the spit8. my bomber of choice is the b26. I didnt decide on any of them due to eny. you can move the eny up or down and still wont make me fly "the higher eny" airplanes. and I think most people dont really care either.
anyway, I think the only way you are gonna make people fly higher eny planes is if you give free money every month. I say about 15 bucks for each 100 sorties and even then I think I would just pay my membership rather than waste what little time I have to play on "higher" eny planes.
