I don't think the issue is people holding the D&D 5E rules to BG3 strictly. The issue is Larian advertised and said several times that BG3 is going to be a game set in D&D, using as much of the 5E rules as the game engine could possibly allow. Larian bought the Baldur's Gate and Dungeons & Dragons license from Wizards of the Coast in order to even make this game, let alone use all the officially named races, deities, NPCs, and so many other things, that demanding they essentially break the setting/contract to make a non-D&D 5E game just because you don't like or understand how the rules translate into a video game just seems... childish to me. And yes, you can play BG3 with your friends, so the statement of how you can't even joke about and riff on your friends for missing constantly is a hugely moot point, even in EA, though I haven't had the opportunity myself to play said multiplayer yet, sadly.
I'm sorry you don't seem to enjoy the game so far, but it was always advertised, marketed, and talked about as a turn based 5E D&D game, so you should have actually listened and paid attention to that, and maybe done some research on how 5E D&D works, especially combat, before going into things with an assumption of how the game should be played. (It's not DOS2, and I hope it never strays closer to being more like that title, but I have no faith in companies.)
