I think your build is a little too over the place with no real 'strengths' anywhere, even broadly.

You're not unlocking many special skills (to train bo's with) at all where you can, you're weakening your ships a certain % etc.

For engineer ground, I find you don't really need many points spent on ground with S4.

If for pve I would say go for it, but pvp, ground or space, I think you'll have issues with your entire build, especially in space.

And the way most of your skills are under 7 points....means hardly any of your ground or space BO skills, are popping at the same effectiveness as the person next to you.
