For dialogues dice rolls are bad. But for combat it could work. The damage rolls are a huge problem in this game. The amount of damage depends on your rolls too so if you are unlucky you do next to nothing damage and your foe can kill you in his turn. To fix this in BG3 is very complicated Larian would have to change the combat system completly. The gap between min damage and max damage seems way to high for the enemies Larian placed in the game. On tactician they almost always hit. Even on the lower difficult settings you can lose a fight within the first round because of bad luck. But dice rolls are still the best mechanic for crpg fights. What would be the alternative?
