I think this is why Larian has expressed a dislike of dice rolls to hit, and did not use them in DoS 2. The problem is that rolling dice is central to Dungeons and Dragons. If you remove the D20 you are basically creating an entirely different game.
You may be able to construct a really good argument that dice are bad for games, but I do not think that you can construct an argument that a diceless video game can be faithful to 5E D&D (or to be honest, any edition of D&D).
