There seems to be an uncomfortably large number of people coalescing around the idea that the goals of BG3 are wrong. That taking 5E as a base and tuning it to make something that would appeal to fans of Divinity Original Sin and tactical combat is just fundamentally something that shouldn't even be attempted. BG3 needs to be a strict interpretation of 5E and nothing else is acceptable. Solasta did it and it appealed to a tiny number of existing fans of 5E so that's evidence it's the only possible solution.
That's a bit of a straw man, isn't it? From what I've seen, majority of the complaints are about it being a DOS game with some ham-fisted DnD elements. There is no 5E base there, just a minimum effort to adapt it to an incompatible system that already existed in the previous games. I would see no issue with the additional Larianism, if they were properly power scaled to the 5E ruleset, and didn't break the fantastical reality.
