I'll bite. Here's what I got.
Wither-classPlasma Destroyer
Carrack Type
2: plasma thruster
1: aethersail
2: holo-field
3: barrier field
1: reinforced hull
naval 1: +1 system slot
naval 2: downgrade to las/plas close in/point defense.
naval 1: fusion artillery
naval 1: suncannon
naval 1: suncannon
naval 1: Grav shear
Heavy 1: Grav Imploder
Heavy 2: Grav-thruster
This ship takes advantage of a few things: Barrier fields are CHEAP, ep wise (5), and a mixed thrust configuration means the aether sail can get shot off and it an still fight while leaving room for other parts. The grav-thruster is obligatory, as with a holo field and a barrier field, it can dance all day at long range.
it could, however, trade -every- weapon slot in for suncannons, for a count of +3 per heavy, which would be a -whithering- broadside. (instead, it mixes in shears and imploders to let the plasma get at chewier systems more easily).
it could probably use more armor, but I see it as either a pack hunter, or pounding to close/mid range after wearing an enemy down.
Edit: a carrack that really wants to can mount 12 whole-ass plasma systems. Thats almost worth considering on its own.
