I haven't read a single post from anyone about wanting an exact tabletop ruleset conversion for BG3. Why are people thinking in such extremes? The vast majority of D&D players are open to homebrew if it plays by the spirit of the rules. If only we could discuss the homebrew rationally without dismissing each other outright with extreme opinions like "Larian should do whatever they want" or "don't change anything". And again, I've not read the latter from anyone.

The problem that many are voicing is Larian not understanding the spirit of the rules. They are simply going too far with their homebrew additions. Surfaces are a good concept for a video game but the implementation is over the top. Same with dipping, high ground and backstab before change. Shoving. Good concepts with poor over the top implementation that promote repetitive tactics. Then there is the type of homebrew that gives out Rogues' Cunning Action to everyone for free that just fails to understand the spirit of the class based system (and multiclassing) on a fundamental level, and is completely unnecessary to enjoy the game.
