Hello everybody. I’m new to this game and I want to know if it’s worth investing in unlockable subclasses (Nak Muay - Rune Caster - Miko - Shinobi - Appraiser), cuz it requires some work to acquire them. I currently have a [Wizard: Cryomancer > Onmyoji > Psychokino] and I’m looking for a build 4fun (preferably Scout or Swordsman). Leave some suggestions in replies 
My current build: https://tos.neet.tv/skill-planner#213k4.254585.2f3a455a85.8a9fb5cae5.1f5f758a
No.
The only thing worth acquire is the unlock thing in your F1. You can freely use voucher by spending money or electric bill.
Do anything you like to do, people around will fun like you as well.
not sure for the other hidden classes. but i recommend buying unlock voucher for Nak Muay and Shinobi, unless you want farm tirelessly for quest items especially for Nak Muay. currently Nak Muay is back to being underwhelming, but Shinobi is getting buffed after maintenance.
