Firing 10 destroyer turrets keeps your energy at a "stalemate", no energy is lost, but none is restored.
I find my loadout to be effective, and I've never missed a mortar shot against a cap, but some may not like it. Missiles are pretty useless in my opinion, as they are very easy to dodge when mounted on anything bigger than GBs. With a good aim, you'll do more damage with guns than missiles, and since the vanilla missile weakness is getting nerfed, it makes regular gun turrets even better. Plus, mortaring bombers that get too close is fun:)
