I assume when you talk about insane G2A range you mean the Skyguard. But there is an excellent reason why it's like that: otherwise aircraft could just press the magic afterburner button and being out of range again. Which regularly happens even right now. It's already hard enough to destroy aircraft with flak. Limiting range would only make sense if damage was way higher than it is. Then most of A2G weapons give ground troops no escape at all. Some have way longer range than most of ground weapons. Esfs and libs can literally make rockets come down from such a distance they are almost untouchable. If I can accept to be lolpodded from beyond range of my ground weapons then aircraft must live with the Skyguard and Burster range. They are just tasting their own medicine besides they don't get 1/2shotted.
