(If this gets locked for being an old necro, I understand, but I just had to post in here again.)
I am SO glad that they changed the D'deridex's BOFf layout to exactly as I was hoping. I was looking forward to flying a D'deridex, and now that it basically has the Fleet Ambassador's BOFF layout on tribble, that 101% sold me on buying the Legacy Pack.
Aft: 3x Romulan Plasma Beam Array Mk XII [Acc] [Dmg]
Engineering Consoles: Borg Console, Zero-Point Energy Conduit, Tachyokinetic Converter
Science Console: 2x Emitter Array [-Th] [Pla]
Tactical: 5x Plasma Infuser Mk XI
Devices: Red Matter Capacitor, Shields Battery
The skills I usually run are AP:O3, B:OL3, B:FAW2, Tac Team 1, Tac Team 2, Torp HY3, some limited healing like Hazards 1, Eng Team 1. EPtW is a must too.
I usually squeeze out about 6500 dps in ISEs with this build. But above all, it's incredibly fun to fly. I had the Defiant cloaking console in there, but with the T5 rep power that cloaks, I replaced it with a better console.
Heh, I'd love to see that Defiant in pugs, just to watch the elitist snobs flip out at a Defiant using beams. Sweet.
I know, I was going to make a "Beams on a Defiant" comment :p
But seeing as how about 95% of the time I have the highest DPS in the PuG, by a factor of double the next person down, that tends to keep em quiet. When there is someone that surpasses me, those are the most fun runs. Goes down in no time!
