Question: I am aware that a Saurian boff with Efficient is a highly prized thing, and they command premium prices on the exchange. Is the Borg boff trait the same statistically and why is Efficient so amazing?
Yes, the Efficient trait on the Borg Engineer is equivalent to the uncommon Efficient Saurian.
The reason they're in so much demand is because:
a) It's currently the only functional officer trait that works in space.
b) The 5-point bonus to all Efficiency skills would cause your ship to generate more power at low settings. Each Efficient officer you gain is about enough to generate 1 more power at the 25 setting.
c) The Efficiency skills also affect a large number of Engineering abilities, such as Emergency Power to Shields.
A player with a full Efficient crew could run a system on a very low setting and use the corresponding Emergency Power ability to maintain 125 power in that system. I have 3 - 4 Efficient officers depending on which Cruiser I use, in addition to having Efficient Captain and various equipment and skills, and I can run my shield system at 30 and maintain 125 shield power with EPtS III.
Indeed, the other space trait for a BO is on humans, and its leadership. Its supposed to do increased repair rate, however its listed as a ground trait, not a space...and doesnt apply to ground equipment either....
Also you can get a male sci borg bo from one of the harder end game missions, that requires a good solid team of 5 or more.
That being said. These officers would not be best used as your away team because they are on the ground and the space trait would not hep them here.
PS the borg also have nural blast, a nice trait on the ground, it can expose and hold them i think, it can be nice, mostly i was thinking of the saurians who dont have it.
