I hate to say this, but there's a fixed set of things you pretty much need to obtain to build the "I win" Federation starship.
Fleet Resilient Shields (if you have a high shield regen build, Fleet Regenerative Shields)
Fleet Warp Cores with [AMP]
Advanced Fleet Weapons with [ACC]x2 [DMG]x2 (Do NOT get Elite Fleet Weapons)
Vulnerability Locator Tactical Consoles
Rare Male Romulan Tactical Officers (Do NOT get Very Rare or Female Officers)
Task Force Omega Reputation:
Omega Force/MACO/Borg Deflector (depending on ship type and build)
Omega Force/MACO/Borg Engine (depending on ship type and build)
Borg Assimilated Console
Borg Kinetic Cutting Beam
New Romulus Reputation:
Zero-Point Energy Conduit Console
Elite Scorpion Fighters (for most hangers)
Nukara Particle Console (only if your ship purely uses beam weapons)
Tachyokinetic Converter Console
Plasmonic Leech Console
Saurian Bridge Officers with Efficient trait
Plan according to this list and you should be fine.
I've decided I am going to build the 'I Win' ship described here. It will be a long term project for me, since I never completed Omega rep, and only get the marks by doing the ground missions on Defera. I have finished all the other reputations and should have access to everything else.
What ship would people recommend I use for this project? I currently fly a JHEC, but was thinking to go with a Fed ship this time. I noticed at some point I bought the Vesta pack, but never used them. Would one of those be a good choice, and if so, which one?
And as a side note, I found that I have THREE Plasmonic Leech consoles in my inventory. I will use one on this build, but would be happy to give the other two away to fleet members who need them. Just give me a shout in fleet chat in game and we can make the trade.
