Son'a Dreadnought

The Son'a Dreadnought seems to have collectors on the sides of its hull. Every 30 seconds or so, it will deploy these collector "fans" and will actually absorb any energy attack to repair hull damage. Unless you have a lot of dps, the battle can go on indefinitely. Time your shots correctly. as well as any aid ships you are able to call in, and you can make short work of this ship.
