ENY never really affects me either, it's just that ENY is a big factor when gaining perks. If I shoot a N1K or a Spit16 down with a 110G or a Ta152, I think I deserve more than just 1.0 perk, sometimes even less. Some of the planes need to have their ENY changed because when compared to other planes, they are completely out matched yet gets more or less the same amount of reward for shooting another plane down.
