I had an interesting private contest with another fleet mate and D'Kora owner tonight.
I had the best success against him with antiproton and polaron. He had the best success against me with the new phased tetryon.
I'm a Tac captain and he is a Sci. I am a new player and he has been playing STO from the beginning and has all the associated legacy/class perks. (at least he was not running any "prototype" weapons which were long removed from the game)
He is a better pilot than me, so even though we had our ships similarly matched, when I ran DC/Turrets, he kicked my butt, since I had trouble keeping my forward guns on him.
When I switched to DBB/BA weapons, I sometimes owned him or held my own very well.
Next, I could not run the Jem Hadar set against him as I kept getting burned down too quick. I had to run full Aegis, which is my best defensive set. I even tried the Borg set and nothing let me survive like the Aegis 3 piece. He was running full Honor Guard XII and Borg console, so he again had a bit of an edge on me in this regard as well.
At the end of the play time, I really appreciated what folks say about STF and PvP. In STFs, it's so much easier to make many builds work well. In a PvP contest, there are so many other factors which can ruin your day, one must fine tune for the challenge at hand.
I did come away from the experience thinking, I would have had a hard time surviving against him with any ship that did not offer some serious self healing and DPS. For my KDF captain, only the D'Kora and Tac Borta seem to fill this niche.
One thing he used a lot was his ability to cloak with the Honor Guard set and jam sensors. So I wondered how things might have been different had I been in a B'Rel.
I don't regret rolling a Tac Captain, but a Sci Captain sure does have an interesting bag of tricks.
Bottom Line.... I'm still very much liking the Polaron build. although there is a time for Cannons and a time for Beams.
Aside... my friend really wants wants a Tholian Orb Weaver. He swares that is going to be the perfect Sci Captain ship.
The thing with polarons is that they lower the power levels to help you do more dps... but the amount they drain is so low per proc , -25 to all systems that it is very difficult to get stacking procs to really make a difference. In short, at 2.5% proc rate your chances of getting two or three procs triggering inside the 5 seconds the power debuff is in place so that they stack is astronomically small.
Antiproton, phaser and disruptor on the other hand have their procs instantly providing a crippling debuff (spike dps, disable subsystem, -10% resist to hull for 10 seconds) the moment it procs.
Polarons are useful only if you have a drain setup. Tyken+polaron+aceton assimilator+drain drones+power siphon type of thing.
Named after a carrier launched before it was ready, without a working air wing and a crew of novices. Sunk on its maiden voyage. Ring a bell Cryptic?
Although I'm a Federation player, I had to add my 2.4 cents.
Polaron build is .... awesome. Personally I use Polaron turrets + 2 Phaser turrets (that way I get the -25 pts to all enemy power levels (Polaron) stacked with the occassional complete loss of one subsystem (Phaser)).
Withing a few seconds of firing at an enemy, you can watch their speed drop as the -25 power levels take effect, making if harder for them to get out of your weapon range, allowing you to do even more damage.
I've experimented with several different energy types, and right now I think the Polaron / Phaser combo works the best (until they tweak the game again in a future patch).
Fleet Admiral T'Kehl - M.A.C.O. Vanguard Force (Sci Odyssey - USS Archimedes)
Fleet Admiral Shivers - M.A.C.O. Vanguard Force (Tac Escort - USS Abraham Lincoln)
The Federation's most successful counter to the Borg and Iconian threats.
As the poster above me said, what happens is that the polaron debuff causes a kind of cascade failure. Because the victim is moving slower, he has less defense, meaning he's taking more damage (and often more polaron procs due to staying in the arc), while his shield resistance is starting to tank, etc. It's definitely a beast of a proc at the moment, even without speccing into or building around it.
I have been having some fun rolling alternate energy types. It's funny how when you switch things up, the grass can seem greener for a few days, then the "buzz" wears off.
I'm still trying to find the perfect DPS/Heal build for my D'Kora as a Tac Captain, something which can be easily tweaked when dropping into a mission to protect freighters or another mission to just blow things up.
I suppose, ideally, one could run any energy type and have fun and be successful.
It's also probably easy to over look the impact of what the other pug players are running, and how that effects over all perceived performance of any build.
I still like the animation of the polaron beams firing. They make me want to zoom in on my view.
