Need advice about loadout...

[AeternusDoleo]

Cerberus style guns take up roughly 50% more to produce the same amount of damage. They do have a higher energy per second use and higher damage per second effect, but in terms of energy efficiency, Cerberussies are hopeless. The only way I see them as effective is to fully load out your battleship with one, shoot your core dry in a short barrage, cruise off, recharge, repeat. But kiting with a battleship tends to not work well due to the long cruise charge times.
They do make good primaries if you want to use a mixed loadout with partial primaries, partial point defense.

Outcast standard turret: 0,35 damage per energy unit
Standard BS turret type 1: 0.38 damage per energy unit
Zoner turret: 0.39 damage per energy unit
Lanehacker turret: 0.40 damage per energy unit
Cerberus turret: 0,28 damage per energy unit

For comparison:
Mortar: 0,149 damage per energy unit
HeavyMortar: 0,146 damage per energy unit
Battlerazor: 0,056 damage per energy unit
Battleship Pulse: 0,082 energy damage per energy unit

While these differences seem small, multiplied over the course of an entire battle, this efficiency difference will add up. Especially if you end up in a hard slog where you don't have time to recharge your energy core.
