AA Tanks Sitting in HQ by C-Ram

Something I have been noticing a lot lately is AA Tanks sitting in their HQ, relatively close to the base AA/C-Ram that automatically shoots down any rockets that enter the area. Despite this, the AA tank's range is large enough that it can still lock on to aircraft half the map away.  As it stands, an AA tank can be nearly invincible for the entire match, because anything that you would shoot at it, like the attack jet's AGM, or anything from the helicopter instantly gets shot down by the C-Ram. There is no way that this is intended by the Devs, right? You can't even drive a tank to go get them because they are so deep in their spawn that you go out of bounds if you try.

As for how I would fix this issue, I'd have it so that no lock on weapons function while you are in your HQ. They could have it so that the C-Ram will shoot down your missiles as well.
