If by balanced you mean completely dominant when large fights are happening then I agree.
But when you put AA weapons on EVERYTHING it becomes nearly impossible for Aircraft to play a role in large fights. Remember, more exists in the game than just one persons playstyle.
You could be right, perhaps it will sway the balance in the other direction. But I for one cannot determine that based on some text in patch notes.
Additionally, there's going to be a huge ESF update coming according to Higby - that will change things even more. Worry less about balance, more about having fun.
