I don't know, it all looked so good on paper. Now that we're experiencing combined land and air battles though it becomes clear it's not really such a fairy tail after all. Planes and ground vehicles are very hard to balance, because one will always be defenseless against the other. A tank (at least not currently) can't defend itself against a dive bomber and will die helplessly, while on the other hand a plane would be incredibly vulnurable to player controlled AA vehicles.
It's sort of a lose-lose situation; dying by something you couldn't do anything about isn't fun for the players, I don't really know how to explain it. I imagine ships/planes action to be too accurate ship AA versus too accurate plane bombs; take any of those features away though and the players will complain about not being able to hit anything. Keep it, and everyone will complain it's too easy to get killled by the other.
It's a game for masses instead of histrocial/realism enthousiasts and as such can not really be balanced with historical factors such as highly inaccurate AA guns/crews or bombs. I hope Gaijin will manage to pull it off but I'll remain pretty skeptical because it will be easy to screw it up.
