Hidden classes will be allowed only for the second and third options, cause they say these classes are lore and exploration related, so you have to have a better knowing of the game, also better access to some maps.
Only Chaplain, this one will not be a Hidden Class anymore. My guess is that Priest will be focused on large scale heals and buffs (as Cleric will allow everyone to properly heal, I guess the basic Heal will be more limited to balance things), and Chaplain will receive some magic damage improvement and some buffs too.
Also: Bullet Marker shooting with Linker or Enchanter outfits will be something so, so weird hahaha
Please IMC, do something with those magical classes that you sent to Scout. It is not because they don’t properly do magical stuff n damage that they don’t do… magic. I know that Linker, Thauma and Enchanter lores tell that they don’t do the magic that other classes do, but it will be so weird to se a Rogue linking players and enchanting equipment
