Idk, I thought BG3 is a really well balanced game, playing Act 2 on Tactition as Berserk with Karlach, Gale & Shadowheart. I've got a couple of tough fights, but been really defeated just once somewhere at the begining by mistake.
BG3 offers some ways to deal with hard encounters, other than just stand & hit till they die...I also love to keep multiple exlosive barrels in my tiny bag for a really hard encounters & throw some goblins over the mountains, makes life easier and much more fun.
