I'm a science officer in the MVAE. My ship is fairly strong, but certainly could use some improvement. I'm open to suggestions. I currently use disruptors, and most of them are now [Acc]x3 so I don't plan to change that.
This build give you ability to reduce a target's speed (TB & TSSE), nice PSW cooldown and ok damage output. I don't believe escorts should be overly defensive w/borg layout, better to invest in speed/defense rating and targeting to apply dps imo. Omega set bonuses are bit OP, but the 3 parts are very good w/o the bonus if you don't mind annoying people w/2 part proc. There are time I use sets from different tiers (eg mkXI mixed w/mkXII) to avoid the partial bonuses.
Doffs 3x Tech, 2x shield Dist
Tac Com: CRF3, BO3, APD, TT
Sci Lt Com: PSW1, HE2, PH1
Eng Com: Aux2Batt, EPTS
Tac Lt: TSSx, TSSy
En Tac: TSSz (or TT)
I'd still stick w/the same layout for gear as the other build, but you could swap on a turret and DBB for the Beam array and 1 DHC. This option gives you more flexibility for disabling subsystems, while having a better spike damage via shortened CRF cooldown/BO3 cooldown, not to mention PSW for interrupting Ext Shields, Evasives.
These are squishy builds, so have the option to swap in more a more tanky boff layout if you're on a poor cross healing team.
Last, not a fan of your skill selection to be honest. It also seems short in space points, have you maxed those or do you like having what you have in ground? Consider putting 3 points in decomplier at least to boost your TSSx and PSW effect durations. I think you can lose some from warp core potential and warp core eff w/o a significant change, same for the eng and shield perfomance SP allocations. I forget what the bottom teir4 sci ability does, but you can probably drop that altogether. Flow cap investment never hurts either and is cheap. Look into boosting your hull resists even just 3 point in those helps.
I do have 2 tac teams, but I'm using APD instead of APO.
You should consider getting rid of APD. APO or APB will serve you better in an escort.
In an escort, ideally, you should be able to bust up your opponent bad before he even has a chance to switch target to you. In a good strike, your opponent will be too busy trying to get his heals working, to even think about returning fire. And when he doesn't return fire, APD doesn't proc on him.
