I got to Tier 5 in the Romulan Reputation system last night and the Omega Reputation tonight. I'm trying to decide what, if any, of the sets or new gear I should get. I'm an engineer in a Defiant-R. I don't PvP, I do STFs, and occasionally fleet missions. My fleet is at tier 3.
Here's the setup I've got now-
3 Antiproton Dual Heavy Cannon Mk XI [CrtD]x2 [Dmg] (old STF weapons) & Omega Plasma Torpedo Launcher
2 Antiproton Turrets MkXI [CrtH]x2 (old STF weapons) & Cutting Beam
MACO Mk XII space set
3 Neutronium Alloy Mk XI
2 Field Generator Mk XI
3 Antiproton Regulator Mk XII & Assimilated Module
Your weapons look all right for taking on the Borg, but like scurry said, take off the technician and add the Shield Disribution officer.
Personally, I'd opt for a Projectile Weapons officer to reduce cooldown on the Omega Plasma Torpedo Launcher
I've got two Projectile Weapons Officers now. Would a third be that much better over the Shield Distribution Officer? Does it impact the recharge time for the Omega Plasma Torpedo Launcher? I know they worked awesome when I was using photon torpedoes, but I wasn't sure they would work on the Omega Plasma.
