I am surprised that as a Tactical Officer, you are using a Cruiser instead of an Escort. Bold choice, I respect that.
Your second build is better than the first one, yet I have a few suggestions, especially if you want to survive in STFs. Before you consider those suggestions, I'd like to remind you, that those are my personal opinions. They are not the law.
1. Increase points on Starship Engine performance and Starship Shield Performance. Your Cruiser is not the most maneuverable, so you want to increase that. Also you want to increase your Shield performance for a better survivabilty.
2. Driver Coil is fine. However, if you want to earn Money during the Tour the Universe Event, you want to increase that to maximum.
3. Particle Generators. Those are great, if you are using Feedback Pulse, Gravity Well or Tyken's Rift. Your BOFF Layout however doesn't show the use of those. So if you are not planning on using them, those points are most likely wasted there.
4. Starship Sensors. In my own opinion, those are not needed unless you plan to do PvP against KDF Player. So just drop them.
With these suggestions, the build would look like this
I hope this is helpful to you.
