i think it is harder to build a spike dmg fed cruiser than a support escort...
only 3 ships come in mind: D'kora, the galaxy X, dreadnought carrier
d'kora was explained already so i leave it at that
the galaxy X may have potential when coming out of cloak with DHC...but it will allways lack high ranking tac boff powers and maneuverability...so i would say forget that ship.
dreadnought carrier has potential to be bursty, but i think it will be hard to bring those weapons on target in PVP.
klingons have it better...fleet vorcha with great boff layout, cloak, DHC
