Most of the pros and cons have already been addressed, but I have a Sci VA who flys in the Prometheus so I'd thought I'd chime in.
First, as other have said, you need to get BOff powers that will help your captain in an escort. Flying an escort is about DPS and moderate surviability. In an STF, for instance, you can sacrifice a little survivability if you have a good team who can pick up your healing a little. In PvE, you can pretty much rip through opponents very easily while running just some healing abilities. In PvP, like STF's, if you are with a good team, you don't need as much survivabilty.
A good basic (and I mean basic) build, you would want your 4 front ports to have 3 cannons or heavy cannons and a torpedo of some kind. Your rear 3 slots would be turrets. I am sure you have played enough to realize that all energy weapons should be the same kind. I would suggest that you spend the C-points and get the "point defense system" that is available on the Sao Pauolo +1 class you can purchace at commander level. The PDS is a very good tool to help you fend off lots of targets (heavy torps included). Just my opinion, anyway
One thing to consider, also, is do you want to do AOE (area of effect) damage or single target damage? If AOE, train your tac BOff's in Cannon: Scatter Volley and Torpedo: Spread. If you prefer single target, than you should be running Cannon: Rapid Fire and Torpedo: High Yield. Other Tactical powers that really help are Attack Pattern: Omega, Tactical Team, and Attack Pattern: Beta.
Some Sci Powers that are good to help you not to pop quickly are Science Team, Hazard Emitters, and Transfer Shield Strength. For Engineering powers, I usually use Engineering Team and Emergency Power to Shields or Emergency Power to Weapons (if I have enough healing). Another that I usually don't use, but is very popular, is Auxillary Power to Structural Integrity Field.
For consoles I generally run the Borg console from "Assimilation", PDS console from the Sao Pauolo Class, three of the tactical beam consoles that match my weapons, and one of the tac consoles that matches my torpedos. For Engineering consoles I like Elecromagnetic Hull Plating and the console that helps Auxillary powers (this one helps your sci powers heal better or hit harder in the case of Subnuc or Gravity Well/Tyken's Rift). If you can afford it, for the remaining Sci console, buy the shield enhancers.
I run my captain in PvP and STF's and I usually do alright using a build like this. As you play it a little more, you might find you like a different set up....Play around with it.
Hope this helps
Edited for grammer and spelling
I've had a MVAM Prometheus in my 'inventory', for my Science toon, for a little while ago, though seldom used it until recently.
I have to say, I have it set up as you describe, with the exception that I have a MkXI [Borg] Quantum launcher as well as turrets aft. Science toon or not, I love the DPS that the Prometheus can put out!
When it comes to picking a ship type, I like to explain things this way. You ship and BOFFS provide 2/3s or what you can do in space. Your Captain adds the other 1/3. Having Ship Type and Captain Profession being the same, gives you one heck of a ship of that type. (i.e. A Cruiser with Engineer Captain is one heck of a survivable ship). But other combinations are equally viable and provide a unique and different style of game play.
My Tactical Captain in her Dreadnaught can crank out massives amount of damage (more much as an Escort). But my 1200+ damage/tic Anti-Proton Beam Arrays will suffice. Oh yeah. That just the base damage. The crits are much, much worse. I'm doing while in the middle of an enemy squaron. She can tank pretty effectively, too.
A Science Captain in an Escort can be a very deadly combo. In PvP, you never know when the SNB will go off. You could be sitting pretty with a lot of Shield and Hull Buffs running and then *POOF*, you're sitting naked as the Escort is making it's attack run all buffed up. And in PvE Photonic Fleet is a great for survivability and a lot of supplementary damage too. And the last, but certainly not least. A buffed up Sensor Scan stacks and multiplies all of the Tatical damage buffs you'd be running.
I'm a level 50 science captain. I have only ever gotten science class ships. I was wondering if it is worth getting an escort class ship for use in some STF missions.
I'm a tactical officer. I have come to prefer cruisers and really like my Odyssey ships and use them the most. I also have a couple of escorts which I use primarily for pvp or just a change of pace. What I"m getting at is the fact that I can hold my own in any ship if it is equipped right.
I highly recommend trying out an escort ship. The speed is nice and dual cannons are very cool.
Thinking of trying my science toon in the Tactical Escort Retro (T5 Defiant) - is this advisable? I've been using the MVAE, and do fine in that - but as per the STO wiki:
"Being science oriented, the Advanced Escort lends itself to shield healing and debuffs and is a better choice for science captains as its additional science console can boost the player's captain abilities"
Now I'll admit, part of my motivation is that I have a second (Tactical) toon, currently at Captain (35) and use the T4 Sao Paulo for that one, so I have some (limited) experience with flying such a ship. Unlocking the T5 version would, obviously, mean that my primary toon could use it, and my second toon would have access to it when reaches T5 - plus I'd be able to equip the quad-cannons from the T4 on in SAND use the Sao Paulo skin.
So - worth doing, or should I just leave my science toon in the MVAE &wait until my tactical toon reaches T5?
i will just say
MVAM + SCI captain Holo Ship ability = 5 pet ships = FUN
the MVAM can do good DPS, has enough engineering and sci abilities to take a bit of damage, and still has room for at least one good offensive sci ability. (i prefer tractor beam repulsors to push borg ships away from where they want to go...)
personally i never liked SCI ships / SCI abilities, just too much *magic wizzard-ish stuff*, a ship has torpedos and phasers and thats what i want to use... i don't do gravity wells and stuff like that, that does not look and/or feel TREK to me.
The Advanced Escort is more Science Originated when compared to it's sister class the Fleet Escort. Teh AE has an extra Ensign Science Bridge Station and an extra Science Console slot. The FE has the exact being Engineering for both. That STOWiki entry was written way before the MVAE was introduced in the game.
The MVAE which is a newer class is much more science oriented with tit's Lt Commander Science Bridge Station. The Bridge Station on the AE is a Lt Commander Tactic Slot. That makes the AE more DPS oritented than the MVAE.
MVAE is the best sci-scort hands down. The MV function is sorta gimmicky and I don't even equip it because i lose a console spot. Your basically paying 2000 C points for the more sci friendly boff layout.
I'm personally a tac officer, and I do have the RSV also. The Recon Sci Vessel is a wonderful ship also if you don't have it. However it's base hull is 4,000 less then any same tier escort and only has two engineering consoles. So although You get 7 sci abilities, and some potentially decent firepower, However, once you get targeted you get dead.
Keep in mind I'm a tactical officer with more sci skill points that I should have.
If you want raw damage output, I think my fleet escort does a better job at that. I don't recall the layout of Defiant-R to recommend it.
