IMO, many more super late war fighters should have a small perk. It would balance the fighters better. I do actually wish perk costs went up instead of canceling out planes/tanks all together.
It is hard for bombers, because once the ENY kicks in, you cannot fly bombers that are worth a damn, and planes with ord also get canceled which makes Jabo very tough.
So any players trying to bomb or jabo my log off. Which also can greatly impact your team if you are one field away from taking it.
One time we had ENY kicks in, one field needed, our CV was right there and all we could roll was F4Fs and A6M3s with hardly any ord. We couldn't take it and couldn't win because every decided to switch to our team for easy perks for the win.
