get rid of ENY limits altogether! Just make the perk price continue to escalate with the diparity in #s, who know's maybe someone wants to up a 1000 pt 262s to fight 50 pt 262s 
or a 500 pt tiger to fight free panzers for that matter
Just a thought, then you can fly whatever ya like, IF you can afford it

It's a catch 22 shreck ... those that cowl and curse at ENY are those who need (or believe that they need) the lower ENY planes to survive.
Low ENY rides means lower perks acquired so they usually have doodily-squat for perk points ...
Low perk count means they can buy high perked rides ... OH NOES !!!
If they can't buy them ... then why would they give a crap if ENY takes them out of play as it does now ?
People who could buy them, all day long, are those who generally fly high ENY planes, who really are never effected by ENY limits and because they fly the high ENY planes ... they usually have a ton of perk stored up.
So ... those who could afford the high perk prices don't really care to fly those planes in the first place and those that would like to fly them ... they can't afford them.
I've got about 36,000+ perk points and could probably fly perk planes 'til my hands bleed ... but you won't find me in one. Every once in awhile I will take one up, but I much prefer my FM2 or F6-F and if ENY does take them out of play I'll up a P-47-D11.
