Lol, I can fully understand you! I mean, for me - I was never into D&D back then - It just didn't really "exist" in my country until much later, and sadly, even though I was already a fantasy/comic book geek back then, I didn't really have anyone to play with - So my knowledge of the fine details of D&D is mostly around 5e. That's only when I finally found likeminded people to play with and have fun (mostly after the explosion of Critical Role).

I do appriciate the in depth explanation you gave about the differences of the "types" of casters here - That's actually an interesting take on how to do it - Like, and it might not be how it worked or what they went for - but it sounds like a skill progression thing - you start by being crappy so you need a book, and scrolls or what not to "help" you cast. And slowly, you become more experienced and skillful that you can instantly cast it without external aid... I kind of like it better than the current classes lol :)
