I'd prefer the actual D&D rules on this, as with many other things Larian have changed.

I don't think Larian fully understand that what makes the class based system work is that other classes can't steal your shtick. Wizards are special because Fighters and Rogues can't cast spells or use scrolls. Clerics are unique because Wizards can't learn their spells. Rogues are cool and distinctive because no one else can Hide or Disengage as a Bonus Action.

And D&D has all the rules to blend these class perks and allow customized character builds in a balanced way already. They don't need to add any freebies. I wish they would just... stop.
