sorry folks, I feel like I am not seeing new comments to posts on the regular. However, if you swap to full 3 piece Iconian, and look into the "Xenotech Powerflow Module" from K-13 that focuses onĀ [EPS] and [Pen] you will have improved your DPS immediately.
Your Skills are good. As Tact. I would not change them at this time.
Your Boff layout is a little confusing to me. Since, you are using cannons for this build I would at least have a rapid fire 2. You can get rid of Heisenberg amplifier, Entropic cascade is much better if you are going temporal. Beam target Aux is also lack luster, I would use attack pattern Omega 1 or rapid fire.
I am not sure who your boffs are, but your Boffs can help a lot too, Romulan SRO from the Embassy could help a bit for tact and if you have the hierarchy boff, use them in the science seat for a cat 2 bonus to DPS.
Here is the adjusted build.
