I'm not sure where you got the impression that this is a game "inspired" by D&D or "based" on D&D. It is 100% meant to be a game that uses the current D&D edition mechanics and that is part of the caveat that the licensing publishers(WotC/Hasbro) have given. There is obviously some leeway to this but even the smallest of changes are already receiving overwhelming backlash by the community. This is reinforced by the fact that they used the BG name in order to market the game. Believe me when I say that if this is not the case then, legally, I could ask for my money back immediately based on the legal precedent of 'honor your advertising'.
That being said, I am fully aboard with dialogue choices being thresholds as opposed to rolls simply because this is objectively superior for the role playing experience and this mechanic is already included in D&D. It is known as "take 10". If the DC for a check is 17 and you have 9 in the relevant skill you can opt to just "take 10" in the roll and instantly pass. This is to remove the chance when it comes to critical skill check when time is not an issue. I understand that you don't enjoy probability but are you aware of how this works in other games? Dice rolls. In other games they have been distilled into pure mathematical equations that are run hundreds of thousands of times in the blink of an eye with variables much large than what is available on dice. Most developers have the clarity of mind to know that this is not something that the player should see or be privy to the details of let alone to shove it in their face like Larian does. What I am saying is that for the most part what bothers you about this mechanic is that you are being made aware of it.
