I'm 51D wouldn't be included in this list?
I think the eny should be dynamic on the planes. If everybody is flying a certain plane is should cost more and one that nobody is flying should have a higher perk bonus. That way there wouldn't be an arbitrarily assigned eny numbers.
I wouldn't be opposed to perking it 5 perks or so...
Probably be a bunch whiners though.
God forbid they can't press X and run when they lose advantage. Funny enough the P51 still doesn't have that great of K/D relative to others because it's the #1 plane flown by newbs.
If the p51 really draws a huge crowd, I wouldn't perk it just because, however, I feel like all of these super later war planes should have a 1-5 perk range. Is it really that hard to save up? No other games make it that easy.
