I've picked Soldier, Resilient and Efficient for my Alien Captain, but the choice for the fourth trait is harder than I thought. I've narrowed it down to Accurate (although I'm not sure a +0.1 increase will help that much) and Warp Theorist - although I'm not really sure what a boost in warp core training will do. I've read that this is a good all-round trait, but would it be a better choice over Accurate?
The following is the above chart with Efficiency (the trait) in addition to Warp Core Training. Rank 7 Performance is omitted due to skill constraints:
Actual Power Setting: Starship Warp Core Training Only/Starship Warp Core Training and Starship <System> Efficiency/Warp Core, Efficiency and Performance
So warp theorist + efficient will help you balance your ship power. Like lets say you use offensive 100weapon, 50shield, 25 engine, 25 aux. With the skills you could have 109/68/51/51. Or you could save points on weapons and shields but still double your aux/engine!
If you want accuracy (+10% btw) I would drop either soldier or resilient. Ground combat is alot easier (as you will have a team with you) unless you want to focus on ground PvP.
