(Pursuit + Self-Destruction)
Drones in Pursuit Mode accelerate toward enemies (prioritizing some mix of proximity, enemy strength, and enemy concentration onscreen) and explode. If you have multiple drones out, they spread to avoid overlaps as much as possible. Explosion damage maybe scales with a combination of hull and weapon damage? Ought to be a larger radius and more damage either way, and has good synergy with Burnout Reactors. Maybe also a buildrate buff? Might be overkill though.
Downside: Either a heavy fire rate malus for the drones, or they don't fire at all (so orbit formation is just to stockpile them/ablative armor).
