[suggestion]cap ship "death imminent" abilities
The abilities cant be used until the cap ship in question is near death, like 1000-1500 health left. One ability could be a suicide crash into another cap ship or starbase/structure for massive damage. Or reactor gone critical dealing splash damge to all nearby ships/structures (friendly or enemy). Or the cap ship could increase its rate of fire and Damge Per Second, the side effect being the cap ship stops repairing itself/shield regeneration and takes more damage from enemy attacks.
