I have to agree with dahminus on your build. For a successful build you want to maximize your firing arc first. In your case go either full beam arrays, or full dual heavy cannons with turrets in the back with a torp thrown in somewhere. Because this is PVE you don't really need the spike damage, but I usually like to run a dual beam bank up front with a beam overload three backing it up. Really isn't much I can say that hasn't been stated above.
You would be better off with a escort/fleet Mogai with more hull and battle cloak. Your build fails to leverage the abilities of the enhanced battle cloak. The T'varo should be a torp and mine boat, and you should not be getting into prolonged dogfights with this ship. Go all transphasic torps front, adapted MACO or KHG, a mine of choice on back with a Breen Cluster Torp, Dispersal Pattern Beta, crit consoles, assimilated console, Rule 62 console, stay cloaked, and blow up your enemies with their shields at full and their hull at 0.
Chingachgook told me, Don't try to understand them; and don't try to make them understand you. For they are a breed apart and make no sense.
