I would suggest that Larian develop a "D&D mode", which actually attempts to implement 5E rules as closely as possible. It doesn't have to be the default setting for the game, but I think Larian is going to alienate a large portion of their potential customer base if they do not do this.
BG3 is being marketed as a D&D game, but early access contains a lot of significant and unnecessary deviations from the the 5E ruleset that are going to alienate people who are expecting a D&D experience. If Larian wants to spend the time and money to "improve" on D&D rules (which is what currently appears to be the case) and implement in a separate mode, this would allow them to do that without alienating the customers that are expecting a faithful implementation of D&D. If possible, I would suggest creating two separate modes / difficulty settings in early access, so Larian can get more constructive feedback, before full release. I don't know the details of the agreement between Larian and Wizards of the Coast, but I have to think that the current implementation of D&D in early access is probably very different from what Wizards of the Coast was originally expecting.
I don't consider myself a hardcore D&D fan, but I do think that a game that is marketed as a D&D video game should at least have an option that tries harder to fully implement D&D rules and mechanics.
i'm not a hardcore dnd fan but myself included i don't like the current implementation (if it hasn't changed since first EA) on the reaction and the bonus action. a d&d game should stay closely to being d&d IMO. also, there's another problem. the art direction, the design, the assets were heavily reused from DOS2 and the look and feel keeps making me thinking that this is a DOS2. the 4 party character limit, the chaining and unchaining character UI are clear evidence.
