Setting aside the aoe gravity well build. I have started switching out scatter volley for cannon rapid fire and taking out gravity well for energy syphon. running full aux for cannons and not boosting flow capaciters beyond 6 this was draining people for 20 pts in each system in pvp and boosting my own power levels by much more.
In pve this build is grate for Donatra, tactical cubes and the borg queen and would boost your weapons power to near full if you realy fell naked without it. the reuse time on energy syphon is a lot better then i rememberd as well.
