Listening to the Vocal minority is always a terrible idea.
Attempting to make it "Better" for them always results in a worse product.
This goes both ways you know.

I really think it's down to turn based combat Larian went with. Their turn based combat is brilliant in D:OS games because you can do a lot more in a single turn whether it's because of no outside factors spells limitation (slots etc) and whether it's because of surfaces and so on that give massively more options to keep greatly affecting flow of combat even outside your turn.
But when you slap on D&D 5e limitations, where every turn is practically "do one thing" most of the time (which often is just a shitty attack or cantrip) and then maybe one additional thing once in a while, top it off with d20 RNG and combine it with Larian's turn based where they throw horde of enemies at you, as if it was D:OS - it quickly becomes super frustrating slog.
Those Woads+Mephits encounter comes to mind or Goblin Temple outside, where you have 1-2 things that are an actual threat and then a sea of trash, so that every 1 round takes a good 2 minutes of time IRL before you can even act and when you do - you just miss half of your shit or simply do some pitiful damage and wait another 2 minutes until you can do anything. *groan*
It worked nicely in D:OS where you could easily mow down several weak enemies in a turn even early on, but in BG3 you just don't have that kind of firepower on top of that blasted d20 RNG.
I really think they should consider real time combat as an option, even if it's just to quickly deal with all that trash after you are effectively done with actual threat in the encounter or alternatively not have these bajillion mephits/goblins/spiderlings/whatever and instead combine them into 2-3 enemies that mean business, while the rest trash that does not stand a chance scatter to the winds in terror. Yes, I'm looking at you 8 HP Novice Bork that does nothing except burn another 10 seconds per turn.
That or they can make some sort of change to speed up all the NPC turns a lot, whether by adding combat speed slider or making some other tweak so that all enemy actors won't take 2 minutes to do their stuff.

I 100% think they need to come up with something to amend these pains, because it is often an unnecessary slog.
