Given that spawn campers are immobile, a strong long range artillery piece, combined with long range spotting abilities (such as from an M8 or similar scouting GV, or long range binocs from the artillery itself, as the ship towers have now) would balance out campers pretty evenly.
I don't remember how far artillery pieces range, but spawning one from a Vbase to shell a certain spawn point half a sector away or so would equate to a delay between fire and impact that would suit anti-camper action specifically.
Such a delay would make hitting the random spawn points before the spawned GV moved a neglectable danger, in spawn areas as they are now.
I don't know that artillery could accurately hit a target the size of our tanks' damage area from as far as 12mi, though the perfectly windless air in AH would allow for it, if any artillery had that much range.
I guess if that's too far, it would make sense from secondary spawn points such as those we had in the previous Crater Tank town (on Trinity?), although reducing artillery pieces to just that would be a shame.
Now, being able to tow them behind any other GV
