In DnD 5e, preparing your spells is done after a Long Rest.
I would like to see something similar in BG3 (link this with my suggestions about making resting not as "free".
Of course now I can jump to camp at any time and take a long rest, but ideally if resting wasn't as easy to do, then picking spells would also be more of a choice.
As it stands now it only matters when you are in combat, and if you encounter something where you want a specific spell you just change it at will.
If resting was more of a choice to do, then spell preparation would matter more too.
Just a thought. Minor issue really.
