If the maps were bigger, if there was a bigger buffer, if enemies couldn't drive or fly into your HQ, and if your HQ was protected by the landscape, it would make things more balanced. Since that isn't the case, it's probably correct that you should be able to shoot out of a HQ if others can shoot in.
Maybe just the C-RAM needs a nerf? Like, no AA in HQ at all, or no AA in HQ if within certain radius of C-RAM? Or, just make C-RAM less effective in general. Add C-RAM cool-downs or randomised targetting ("bloom").
I call it C-RAM cause that is what it was called in my real-life experience.
For me the CRAM doesn't even work when I need it, If I have a jet on my tail and I can't shake it I will fly over the base hoping the CRAM might make them break off but no the CRAM stays silent but If I am following a jet to the enemy base their CRAM is a different story and shreds me alive.
