the ship stats look fine but perhaps it should be more like the warlock:
replace the SFOS warlocks laser pulse arrays with your mini beams, but only AP and range of 12" max as even the nemesis doesnt have that long a range on mini beams.
so would have a 4AD TD, SAP, boresighted beam
fore and aft railguns as per warlock
all arcs with Q-lasers: AP, TL, MB, range 12" same AD as SFOS warlocks laser/pulse
turreted particle beam as per SFOS warlock
missile rack as you have it, 4AD, only slow loading once crippled
when you add in the fact your Nike has HELtrack and self repair also this makes it still superior to the SFOS warlock, especially as twin linked mini beams instead of laser/pulse arrays but makes it a good warship instead of the armageddon ship you are currently heading for
