In order to remove this problem from PvE and RP servers, it would be preferable to remove the PvP Achievements from the Locations (Planets) section and place them under the PvP Section.
By placing PvP requirements under specific planets, you make it impossible for non-PvP'ers to reach 100% for those planets.
And in a related note, remove the PvP requirements from HK-51 as well - why is he the only companion with a PvP requirement - which again, make it impossible for non-PvP'ers to reach 100% with him.
