I've yet to acquire the khg set, all I've gotten are those lock boxes, but that shouldn't be the case anymore since they are gone now I have been planning on keeping 3 pieces of the Borg gear and top it off with the khg shields, but now since I am under cloak 95% of the time I don't need that regenerative Borg buff. I am going full khg as soon as the drops allow for it.
