I’ve been thinking about ability scores.
The ability scores are used to determine the modifiers used for combat bonuses, saving throws, and other checks. Beyond that, though, the scores themselves seem pointless. No one cares that your character’s strength is 14; we just want to know that you get a +1 to hit. If that’s the case, why bother with the score? Why not just roll up the modifier and use that as your score?
