Ha! Yeah ... overdid the mount layout with respect to 'vanilla balance', fell short of a few OPs in refit. Nice to play around, though.
I'm not actually so sure of that - it's roughly comparable to the Hammerhead destroyer or the Falcon light cruiser; it's got - judging just by mounts - slightly more forward firepower than either, but as a destroyer-sized cousin to the Brawler frigate, that's not that bad.
If I were trying to scale it back, though, I'd consider swapping the medium energy hardpoints for small missile hardpoints, and replacing the medium missile turrets with either medium energy (to maintain current weapon balance) or possibly medium universal (if you want the flexibility to go either missileboat or uber-brawler).
...I probably wouldn't give it the EMP emitter as a system, though; for one thing, that makes it scary in player hands (near-immunity to missiles), but it also doesn't work well under AI control on something with some actual firepower, since the AI will blithely activate EMP whenever it can - locking itself out of firing its main guns. Might be tempting to give it, say, horrible 1.4 efficiency shields... and the fortress shield as a system. Don't know how well the AI would use that, but it'd at least amuse me.
