I've been playing the game for a while and was in null sec for almost a year. My former corp had a tatara with unknown to me rigs in place for refinement. I was able to refine ores at 86 percent efficiency with my level 4 per ore skill levels and a plus 2 percent implant. Now I leave nullsec and venture back into HiSec to start my own corp and I have noticed that no one anywhere has that kind of efficiency. I spent the better part of the day in Amarr, Jita, and Dodixie space running around using the structure browser trying to find a Tatara that has this kind of efficiency. Does this magical unicorn exist in hi-sec? or is it just something for rich alliances deep in Null Sec? If you know a Tatara that has the highest efficiency in hi-sec please let me know. It would be very helpful and keep me from having to waste a crap ton of time chasing it down. Thanks for reading this and your help if given.
