Lets face it, dealing 3-7dmg to a target that has 40-50hp when you can cast 13-20dmg spells is just never going to happen. It needs a buff, especially at lower levels.
Okay, so your suggestions suddenly make a lot more sense within this context.
A lot of what you say seems to indicate that you think things in this game aren't dying quickly enough, but maybe the developers don't want things to die that quickly. And that gets into the topic of how the issues are more with Larian's current implementation of things rather than the source material itself, because it's widely known that Larian actually lowered enemy AC because they thought people missing was unfun. However, they increased enemy HP to compensate, which ALSO lead to a new balancing problem with how cantrip damage is less impactful than they normally are, and that spells with saving throws are suddenly worse than spells that make attack rolls in the vast majority of situations. Not to mention that party HP growth is largely still the same, so that enemy mage throwing a fireball spell at you would probably completely wreck you, while it'd barely result in a dent if you were to do the same to them.
If game balancing really is your career, you should really look into why the current system is the way it is before passing judgement on what needs to be changed, rather than blindly suggesting numerical changes with seeming little regard to how it'd interact with the rest of the game. BG3 is more complicated than most because it's half Larian homebrew and half source material, and there is a reason most believe that the larger issues lie within the homebrew system and lack of certain source material options instead of an issue with the source material itself.
(Not going to lie, I really
wish I could get a career in game balance, ha. Or at least some kind of consultant. Also, as a nice thought exercise to help you, you should look into analyzing balance in MMOs, as that's how I started out. I say this because they are usually historically bad, usually by design per the nature of being live service games, so analyzing and understanding what happens there makes it a lot easier to come up with more effective and focused suggestions in literally every other type of game. :P)
