They clearly believed some changes were necessary for the benefit of the computer game version. They are the game developers here - we are not. It’s their game & their vision of how this d&d world is best played in pc version. You don’t have to like it - but it is what it is.
What we know is that they don't like the "miss" too often thing. And I'm really fine with custom mechanics (such as surfaces or backstab) that give players more tactical options to increase our % to hit.
But actually the game doesn't feel D&D at all in combats because "their vision" completely altered what D&D is.
Of course no one knows if their will is to create a D&D game in a Larian setting or a Larian game in a D&D setting.
