I've no problem having holocrons exist, I don't want the Jedi or Sith to fall-out, I want them to essentially re-rise by themselves, come out and train themselves rather than by others. That way anyone could take on anyone, mostly. Instead of extremely overly OP Sith can't be defeated cliche.

If you guys want to go the way of the Sith, sure, nothing would really change except the planet. The difference being you'd have to travel to find crystals for lightsabers.
