I understand that a percentage number is easy to understand.... but in DnD, you don't know what the AC of an enemy is, and therefore you don't know what your chance to hit is. Information about advantage/disadvatage alone should be enough, and the AC of an enemy can always be estimated roughly (are they using a shield, wearing heavy armour, etc.)
Do you guys have any suggestions on how Larian could improve/replace this system?
