I'm about to start toying with the Lt. Tac ability since honestly Cannon spread with Single cannons is a joke. I'm thinking a plasma torpedo and torpedo spread might get the job done.
Erase Tyken's from your memory. Seriously.
Unless you're running Tyken's 3 on a Sci is 5 Flow Caps. And even then, don't even think about it for more than a second - the drain is pathetic and it's broken so that it doesn't get buffed by the Flow Caps.
Dump Aceton Beam. Pick up RSP or Aux to SIF instead.
You're also pounding out 4 Teams... any more than 2 is a waste. 1 TacTeam and 1 EngTeam is going to be maxing out your CDs as it is. Drop ET 1 and go for EPtW, or drop ET 3 and go pick up the Aux to SIF/RSP that you don't have from leaving Aceton.
Devs would like a concise list of things that are broken and not working currently, so here's a short list for PvP: Neutronic Torpedoes, Ionic Turbulence, Surgical Strikes (including Faeht firing through cloak), PartGen stacking and CrtH being boosted to absurd levels.
