Agree, but not for act 1.
Would be to boring and eventually force the player to explore the regions of act 1 in a certain order.
Moreover, playing with a rather weak party and being short of ressources forces the player (me) to find other ways to be successful, including not avoiding the fights of course.
BG3 has a sophisticated game mechanic - which would be unnecessary and futile when playing with an overpowered party.
"You can now throw objects or characters that weigh up to three times your Strength ability score" might be such a rule to make it too easy - though maybe fun at the first glance and first playthrough.
Also having too many actions per turn makes the game somewhat too boring, as if you had a fountain with speed potion.
(shudder)
EA includes act 1 only. so either in act 1 or full release. maybe lvl 5 would unlock if the shadowlands are open for testing.
