I don't mind some of the effects, but there are too many of them, and way too overused. Maybe its for testing, but in every fight there is some version of a pool of acid/poison/fire and its just overdone. I have never in decades of playing D&D, any version, witness so much acid/poison usage than in a handful of hours in BG3. At least tone it down some. Not every goblin should be throwing vials of poison/acid and fire arrow explosions like crazy.
