Larian has to try to balance BG3 as a 5e game while still being fun as a videogame to someone who has no experience with 5e, which can be difficult. But genuinely closer to 5e sounds to me like it'll achieve both.
Ironically, from the posts I have seen. The people that have little to no 5E experience are enjoying the game a lot, and the people that are knowledgeable in 5e are the people with the problems. People that don't have 5e experience see this as a dungeons and dragons game, with good story telling, and do not get hung up on translations of rules. While the hardcore 5e crowd are the ones that seem to despise the game and go on about Solasta being so great.
Just thought this sentence was slightly off.
