This game isn't DND, and doesn't have to follow the ruleset and it's their choice. Larian have creative freedom, and after playing DOS2 quite a lot i think they know what they are doing and have faith. Trust the method behind the madness, but understand no matter which way they go, not everyone will be happy and if you come to the game expecting a 1:1 DND clone you've already set yourself up for disappointment.
