I want to know what is the diffrence between all jedi trait like :

difference between lord sith and jedi knight ??

or jedi knight and padawan jedi ?

maybe you got faster Force XP ?

so what is the best trait for Jedi and Sith ?? Consular ? Jedi Master ?

and what is Grey trait like Grey Sage, Grey padawan, Grey Jedi ?

Do you need to put Force sencitive if you already put a Jedi/Sith trait before ??
