I'd agree to use gattlin units and stick to gattlin tanks not the stationary base defenses. The tanks are taken out easily by the auroa's but they are wayyyy cheaper to replace and are not rendered useless by getting rid of your power. Just make sure you keep them spread apart and if facing mainly auroa's keep them moving with waypoints (alt + left click) so when the auroa drops it's bomb it will miss the tank. The tank will shoot at half it's normal rate if moving but i would say it's worth it if it keeps the tank alive. If he's losing $2500 auroa's to kill your $800 gattlin tanks then you are doing well
