More of a philosophical question, but wanted to get the community opinion on this, since my group has built the application described below and we currently use it. I, however, have some doubts as to whether it makes sense to allow it during gameplay.
Suppose I had an application that allowed the user to enter any combination of dice, alongside any extra surges or bonuses that might get added during an attack. Additionally, the user could enter the defense dice (i.e. a single black die, a single white die, two black dice, etc) and any other extra bonuses that might get included in the defense. The application outputs the probability of dealing 1 damage, 2 damage, missing, etc.
Would it be a good idea to allow players to use this tool during the campaign missions, or does it offer too large a benefit? Does using it remove an element of skill that one should expect a player to exercise, analogous to knowing when to hit in blackjack, or knowing when to fold during a poker game, or is it just another legitimate aid, like knowing the contents of the deck before you play?
