Are airplanes too strong?

[Weasel]

I used air once and they did nothing for me (I had 4 of them). I don't allow them because there is no AAA in the game. As for unfair buys, that is why I insist on tank restrictions before buying for both sides, like our game, it ensures a level playing field instead of relying on the rarity which really hurts the US player but not the German (zero rarity panther).
