I noticed that in KoTOR 1 there's a lot of Sith Apprentices and Dark Jedi that you have interactions/battles with, but from what I understand the term "Dark Jedi" is used for practitioners of the darker aspects of the force that have no allegiance to anyone but themselves, they are mostly turned Jedi that have no specific affiliation with a certain group. This is what I've picked up from the Darth Bane novels anyway.
So is it correct to call the random Dark Jedi you encounter Dark Jedi and not something like Sith Acolyte, or Sith Student / Apprentice? And maybe change the names of Sith Apprentices to Sith lords or something like that. Even in Dark Malaks/ Revans army there should be Marauders/Assassins and Sith lords. Just my thoughts.
