Agree 100%. Won't say that the tanking totally sucks but it could be a lot better. A better damage model, a few more tanks, a tank town would be a great addition.
GVs are such easy prey to aircraft that it is often hard to get a good GV battle going. Nothing like getting a bunch of kills so some bomb**** or a IL2 decides to get a easy score. Unlike air to air combat there is vertually no defence in a tank. Can't hide. Can't run fast enough, no protective camouflage. In short the game balance is off when it comes to GV/Aircraft. Time to give the GVs their own space.
