In regards to this article https://treeofsavior.com/page/news/view.php?n=1116 , they mention that
"We’re doing away with advancement quests for any new classes to come. Instead, we’re opting for a system where your character will have to fulfill certain requirements before talking to the Class Master in order to advance. This is similar to how current hidden classes work, although the requirements won’t be as difficult to achieve.
Existing classes, as well, will no longer require advancement quests; after reaching Class Level 15, you can simply select a class from the menu to advance automatically. At this point you will also be given the option to warp to the corresponding Class Master. As for the advancement quests currently in the game, we have plans to renew them and add them as regular subquests offered by the Class Masters."
Will this be extended to hidden classes as well? Such as Shinobi or Miko. It’d be nice if we can just advance to those classes without doing the quests.
