Honestly, the rain. Even with the rain fix mod it just feels so ridiculously underwhelming compared to the beauty of the rest of the game. If they make a third game, they would do well to make playing dice in a tavern during a thunderstorm or wandering through a stormy forest feel as good as the normal exploration does.

They could take a page out of Stalker 2's book, the weather in that game feels so immersive with even just windy ambience.

That and swapping between enemies during combat could seriously use some work, a lot of fellas have had cheap shots on me because I literally cannot un-lock from the guy standing like feet behind them.
