I have a couple BOs that have the efficient trait but I only got them from that leveling quest, I can't seem to find any in the exchange --- which is a very painful mouseover search btw. the vendors don't have them either.
Rare Saurians are the only ones I've seen. At some point I think other races had the trait available, but for now it seems it can only pop for rare Saurians.
If you pre-ordered from Amazon.com, you received a (liberated) Borg bridge officer as a bonus. Efficient was one of its inherent traits. Since they can't be traded, and you presumably didn't pre-order from Amazon, it's a moot point.
It was a Preorder 'Perk' exclusive to Amazon, and is no longer available...
I still don't know why they make it a 'pre-order' only perk. Sorry if I got your hopes up. You can still buy a "Amazon Pre-order" of the game off of eBay if you want. I just can't promise how much you'll pay for it.
I found a "Common" Saurian Engineering Bridge Officer on the Exchange quite early, during Head Start and have kept him since but, it now seems almost impossible to find another.
I have always hoped that Cryptic would introduce more BOffs with more Space Traits, perhaps they will, only time will tell.
