These fights also likely need to be less horde mode. For reference, a standard goblin has a CR of 1/4th, which means for a party of 4 lvl 2 players, 4 goblins is a medium encounter, 6 is hard, 8 is deadly. 4 gnolls is also deadly. Mindflayer is CR 7, super deadly. 2 phase spiders CR 3 and 2 Ettercaps CR 2, deadly again.
Most every encounter in BG3 is in the deadly category or even with the cap of level 4, hard. There are no, or almost no easy or medium encounters anywhere in the EA. And that is without considering that many monsters (especially goblins) are all carrying super overtuned Alchemical and magical area of affect throwables that in standard 5E they typically do not have.
So yes, I agree, the encounters desperately need some tuning, and that is before calculating in areas that Larian haven't implemented the rules entirely or accurately as they are in 5E also throwing the balance into disarray.
