I don't necessarily think people are totally opposed to house rules. But the house rules need to be good. A lot of the "house rules" Larian has, really, really aren't. They make gameplay wonky and force even more house rules elsewhere to try and keep the building that was originally fairly balanced from toppling over.
It's such a minor but super simple example, but firebolt is utterly broken. Its continuous unavoidable damage just isn't fun, or clever, it's irritating and makes for a negative play experience. Another example of a dumb rule change is rogues second bonus action.
then you have awkward mechanics that came from divinity like selecting a power, getting a weird animation then having to randomly click the screen to actually activate the power (dash is a good example, as is second wind). It's clunky.
Comparative to most other RPGs out there, BG3 looks and sounds excellent, and there are moments of good and fun gameplay. But they are moments buried among a bunch of weird and awkward mechanics and design decisions.
Totally agree with that, the problem is not adding house rules, it's adding bad ones.
Another example is the shove action as a bonus action, shoving, aka oneshoting bosses, can be powerful but it should need a real investment like an action, in current state, you can act normally and try to instant kill everything "just in case"
