Generic random encounters would be horrible in a game like this. BG3 has a very small number of encounters, but in exchange they are generally unique and take a long time. This design is incompatible with random generic trash.
Agreed. This game will take million hours for me to play through as it is and random trash would make it even longer. And any leveling curve should not rely any exp from random encounters.
So configurable no exp random encounters would be ok for me.
