My Modified Disciple mod, i would recommend a new game due to the class change but i wouldn't say it would be mandatory.
From the Readme:
Knights of the Old Republic: The Sith Lords Companion modification.
Most people tend to just bench Disciple, he is TSL's Juhani it very much seems.
So i decided to make him more "useful" and playable. Originally Mical started off as a soldier class then changed to a jedi consular,
this is one of the key reasons as to his "benching", it is a horrible combo, so i decided to change his starting class to scoundrel so when he necomes a consular,
he, in theory, will be better for you as a companion. i also re-skin him to resemble a Mirialan, he has dark side transitions and portraits to match.
Run the "improved Disciple.exe" and when prompted, click on the SWotOR2 installation folder, NOT the ovveride folder!
