Please please please explain to me, what I'm doing wrong!! On the mission "Preemptive Strike" I can't kill those D'deridex Defenders! Either from max distance or in its face, it won't die. I'll literally spend 20 minutes on one ship. I'll take it's shields down and bring it down to 58% (MAX), 2 seconds later, It's up to 78%, then back to 90%. So after 20 minutes I'm back to square one.......
One problem is your escort is not built like an escort. They can equip Dual Cannons or Dual Heavy Cannons for a reason...they are fast and manuverable.
And Phasers for the Jem hadar set? You are wasting the bonuses you get from the entire set. Polaron weapon are needed for the full bonuses.
Also, you don't have any consoles to improve Weapon damage, get some.
In all, replace your weapons with Dual Heavy Cannons and maximize their damage and maximize your power levels for attacking purposes. 100/25/50/25 is the optimum set up for your power levels if you fly escorts. Cannons in the front, Turrets in the back.
Most of the community will back up these words, as I am a Noob. But a helpful noob.
Still no dice, that Warbird is pretending my shots are marshmallows. I've got to Dual Heavy Cannons and One Torp up front and a phaser and torp on the back. And I ditched the Jem' Hadar stuff for the standard stuff.
All you need to do is get in close above, below or to the side of the Romulan ship and she can't fire any of those nasty heavy plasmas.
So long as you can put out enough raw or bleedthrough DPS to get through the shields or damage the hull, it's an eventual battle to the death.
I'm known to use escorts with beam overloads just for kicks and despite having no DHCs a beam and torpedo build (light cruiser style) can make use of much more of the escort's maneuverability to evade enemy torpedoes and weapons fire while swinging through all shield facings. Tetyron weapons are best for cutting through the strong shields on Romulan ships and then follow up with a quantum salvo once you're in. Don't waste torpedoes vs active shield facings.
DHCs means you need to go toe to toe with sustained enemy fire while pumping out max regen to the forward shield facing. By far the most efficient way to destroy things in the minimum time but doesn't mean its the most enjoyable
At this level due to the layout of Cannon skills I recommend running
Torpedo, Quantums would be better than Photon.
Dual Beam Bank
Dual Beam Bank
2 Turrets, since rear facing weapons and broardsides are not something escorts do.
Carry a Shield battery, since you have an empty device slot. Detrium is better but.
The Biofunction console does a great job of keeping your crew levels up, shame Crew does next to nothing for any ship in this game. Get a Countermeasure Console since you have Jam Sensors.
Phaser relays or even generic energy console in the Tac slots, Having them empty is costing you DPS and as an Escort that's your bread and butter.
Redo your BOFFs
Tac Team 1 > High Yield Torp 2 > Beam Overload 3
Tac Team 1
Beam Overload, Beam Fire at Will and Torpedo Spread are all valid options but, I recommend Tac Team 1.
Emergency Power to Shields 1 > Reverse Shield Polarity 1
Jam Sensors 1 > Hazzard Emitters 2
When you start an Attack run, Pop Tac team to auto redistribute your shields, than hit Alpha Pattern, Beam Overload and High Yield. Kill shields torpedo Hull and it should be dead or close to it. Keep hitting the Tac team to keep your shields under control and you can Use Tac Team and Reverse Shield Polarity as an Emergency Shield regen. Hazzard Emitters is because there will be lots of Hull fire and it's a better heal than Eng Team. EPtS for when shields take a bit of damage.
If it lives and you start taking damage run away with Evasive Manuvers and do another attack run.
You can use an Aux battery to boost your heals or a Weapon Battery to instantly recover from the Beam Overload.
The Jem'Hadar set is fine, but Polaron are late in the game so you won't have access to them and Tetryon could be quite expensive. If you want you can use a pair of Dual Heavy Cannons and Cannon Rapid Fire 2, but Beams might be the way to go now. Although Cannons will boost both your turrets and DHC's while BO3 only helps the first beam shot but it is at 850% damage.
