I’ve always loved the idea behind the Valley of the Jedi. It has a blatant fantasy element to it which new SW always seem to avoid. I especially felt it was a good inclusion to the lore when Jedi Outcast came out, considering how it was the same time that Lucas was adding stuff like Midichlorians to the canon with the PT.

Also, was Korriban supposed to be a well-known planet? I always got the impression that it’s location was kind of a secret. I also think the Jedi/Sith part of the EU would have been kind of boring if there weren’t any “evil” places to go to. SW is essentially just LOTR in space, with planets instead of countries/lands’. And I’m sure they could have made up some decent lore excuse for why you wouldn’t want to “nuke” a dark side planet like Korriban or Dromund Kass. Besides, didn’t the Jedi think they killed all the Sith? So why even bother?
