Designed when phase phase technology was unknown and phase detectors were not a standard of every sensor package, this cruiser has lost the advantage of surprise - but retains a dangerous and flexible weapons loadout.
Certain unnerving psychological phenomena have been reported by sensitive crew members after enduring many rapid phase-shifts in combat conditions. Domain Navy reports on the subject were never declassified and are thought to have been lost since the Collapse.
A fighter strike on a Doom that is in the middle of its allied ships may indeed be a suicide run but the resulting friendly fire from Doom mine strikes may well be worth it.
Alternatively while in phase, a PC controlled ship can use its PD weapons to coat the area in which Doom is shifted in. The AI will not try to exit phase in this situation resulting in it overloading itself, or coming close enough where a few kinetic shots should do the trick
