Mode without cas and AA spam

Maybe more of a question but why cant we get a mode without overpowerd cas and annoying AA spam its a tank game isnt it. Its just like having a good round and then there spawns some AGM in your face and thats it and since Im not the best player means Im not sniping planes out of air with my 120mm gun its just annoying and most of the time you are the only one with an AA and cant do anything. How about nerfing it more down so they are not able to restock maximum 2-3 players doing cas?
