Ground RB should be Ground only

Title pretty much explains it. Top tier Ground battles are by far the most annoying when it comes to aircraft. Nothing irritates me more than spawning my AA just incase they bring helis at the start just for them not to or dying once to a heli then not being able to kill him with AA because he sits 10km out just above the heli spawn constantly launching missiles across the map. Then there are the planes which everyone just flys on the hard deck so you can’t radar or missile lock them either. It ruins the purpose of why I play ground, the TANKS! They should at least up the cost of helis and planes (1250 sp minimum) or give us a mode solely dedicated to tanks only.
