Dude it isnāt a @Karjalainen thread unless it gets super derailed lol, donāt worry about it.
The problem with cross class progression is that while you could say they could make diferent skills depending on the class tree you get it from it goes against the main desing philosify IMC has for this game: Create your own unique role based off your archetype of choosing and the options it has.
If there where shared classes a good chunk of said uniqueness would be lost no matter how much you change its skills, itās just how it is.
ALSO, for you two and everyone that goes āāReligion related classes shouls all be in Cleric and Taoist has nothing to do with Wizardāā, this is you people not paying attention the the worldbuilding of the game.
When you have the time and access to the ame do yourself a favor and go to the Pyromancer Masterās house/office/whatever in Klaipeda and read the books there, itās the earlier point where you can read about the fact that all magic in ToS is based off the blessings of the goddesses. Basically Wizards use them just as much as Clerics, just in a diferent way.
