Harbinger

Right from its very appearance on a battlefield, the Harbinger proclaims its status as a massive weapon, a laser burning through the heart of the ungodly. Everything about it exhibits its focused intent, from the lights on its nose and wings that root out infidels, to the large number of lasers that serve to destroy them. Should any heathens be left alive after the Harbinger's initial assault, its drones will take care of them.

Battlecruisers carry battleship-grade weapons on a cruiser-sized hull, giving them a damage output well above their price. The compromise is mobility: they align and warp slowly enough that disengaging from a bad fight is rarely an option.
