Ladies and Gentlemen, I introduce you to what I affectionately call the Romulan Flash-Bang.
Using a top tier Romulan science ship, use a grav well 3 once your singularity meter is full and immediately fly at it at fullspeed. Once you arrive at the center of the grav well, use your singularity jump. Use spread torp on a rear torp and watch large numbers of enemies die. You will be doing well over 2k DPS from the grav well + singularity with good skills and high aux in addition to any other dmg from spread torp and weapons.
There is obviously more you can add to this and more ways to liven it up, but it wouldn't be any fun if I gave away everything, now would it?
That works... I tend to pull off the Well of Doom instead... Attack Pattern Alpha, Omega, Tactical Fleet, Fire on my Mark, Decloak and fire off my D'Deridex's mobile singularity fire off a quantum spread II into the mix, fly at the area of devastation then Singularity Jump past and fire my Bio-Neural back at them OR Evasive through them and blast with a fully charged Plasma Shockwave before the secondary explosion hits.
