Depending on your spec, I recommend planting 9's in all T3 efficiency power levels except Shield, and have your power levels diverted to shields whilst your 50% at Auxilary. By decreasing Shield power level and increasing Auxilary power level slightly, youll be able to match them around the 95ish mark. Leave Weapons and Engines with 9's in Efficiency and T4 & 5 9's for better power level performance.
The jist of this build is Shield stripping/tanking. Leave your Fighters and BoP's to do the rest of blowing enemy ships up. If you have flown at best a Galaxy in STO in you'll handle the Vo'Quv turning no problem however if your used to an escort, then you will have much longer to adapt.
All in all, go for Engineer for more tanky abilities and a Science for a more Carrier/Support feeling (it is Science Orientated after all).
