An ELO system? Higher up the scale, the better you are, the better you are, the less rewarding 5.0 ENY planes are. And vice versa.
We have a better system - the community knows who the decent sticks are, and generally most don't sit in 5 eny rides.
Some do I'm sure, I know Hymi is a crafty Spit16 pilot for example, but he will give you a very good dogfight.
I mainly fly anything above 20 Eny for kicks, what good is limiting my 5 eny rides? nothing - except when I see a horde and want to up a 262 I can't now.
This system would be to much and ultimately cause to many problems, we have an ENY system now and it works, I suggested a while back of raising the
ENY to 60 for example, which means Lower ENY aircraft score no perks - and high ones are well rewarded - and even at 40 ENY - its still pretty nice - 8 perks for nailing a P51 or Such, however I think raising the ENY a little would be better off since Its pretty tough to catch a 190D9 or 51 unless you have alt.
I suggested also re-scaling the ENY list - 5eny to 60eny - the Main rides get bumped to 5 Eny, and everything else re-vamped.
Using Lusche's ride statistic pretty much says what ENY the plane will be, more use the plane gets - the lower ENY, this would force some
who want perks to actually step out of the cheap kills, and learn.
Frankly the perk system won't matter to any veteran pilots, I have roughly above 7,000 fighter perks and 3900 GV perks, I would love to see some more perk rides to spend $$$ on.
Edit: For example a 4x hispano P-51 for lets say 40-50 perks? (just an idea)
