The current dice system of the game is very poor. Let us, the player, customize our experience:
Here some ideas:
1) Let us choose: Mouse Over when taking action: Armor Class, Saving Throws or %.
2) Let us choose: UI Feedback Showing Dices or Not
3) Let us chosse: UI Animation: Animated Rolls, Just Numbers or just in the log.
Here some video of a better designed system at alpha. I think Larian can do even better since their CEO uses Plate Armor.
