That I think is a great question - as I mentioned before, when I played BG3 upon release I didn’t get an impression that was anything missing that Larian meant to add. I had narrative and design issues, but those were issues with what WAS in the game, rather than what WASN’T. I would also like to hear examples of “bugs” people mention. I didn’t encounter many in my playthrough almost a year ago now.
I've played BG3 on release and had a lot of bugs in act three, both with quests and gameplay. Some of the quest bugs got fixed (like Gortash battle), some did not (like Ravengard's dialogue). On a side note, even though the game gives you a story reason to kill Gortash asap, if you do so too early it will break a lot of quests, and this is still not fixed.
Gameplay issues examples: camera not showing floor in some houses in combat, companions or summons who have the flight ability not jumping or flying across sometimes, big animal companions getting stuck in places (cannot find path), enemies getting hostile & attacking through walls.
Also, I have played the game with mouse & keyboard before, now I have tried a controller and I am baffled they would release the radial menu in such state. Not only is it very messy, recast abilities like hex don't even show up on their own, I have to add them manually each time before using.
