I think another way of looking at it is progression ranking.

For example: Swordswan or Warrior job class is prerequisite to Knight; Thief is for Rogue; Assassin is for Master Assassin. That would cover the relationship of Base and High types.

The safest to assume as Rare type is Ainz's Eclipse class which has a complicated mix of prerequisite Base and High classes.
