To some extent i agree, its very powerful in a headon, you can sparrow roll if you have enough speed but only really once
Tis a compression issue more than anything else though
You can kinda get away with being lower alt if you makr big sweeping turns/passes around the battlefield, using horizontal distance instead of vertical, getting people to turn to slow them down instead of getting them to climb
Ehhh its not very consequential, but if you really wanna have fun in an f4, the kurnass and even kurnass 2000 are quite good, both basically do the same thing, and the aim9g suits the f4 a lot more than aim9j does cause of the extra range yu can be more opportunistic with them
