The Crimson Binome
Hero
We know for a fact that NPCs use the same method of ability generation as PCs do, because it's in the rulebook. The specifics vary by edition, but there's never been an edition (that I know of) where their base distribution was worse than 3d6. When you see an NPC with 10s and 11s across the board, that is the average of 3d6, just without the variance.The rolling of ability scores or the use of point buy assumes that the person is exceptional or heroic to begin with. Your average commoner is exactly that, average in most things with perhaps one ability that is higher or lower. That helps define who they are. Do you really think that one out of every 216 people has the strength of Conan? If so, then that is a greater disconnect with statistical probability than was insinuated about me.
I'm not necessarily talking about commoners, though. Your average commoner isn't equally likely to have Strength 3 or Strength 18. Your average farmer or blacksmith probably has a 16, while your average seamstress or scribe might have a 5. If you're talented enough to have an 18, then you probably have a job where it matters; Strength 18 would make an excellent blacksmith or guard captain. It's only the population as a whole which conforms to the 3d6 distribution.
And even then, that lucky blacksmith with Strength 18 isn't as strong as the legendary Conan, because Conan never has just Strength 18. In AD&D, he had 18/00. In 3E, he started with an 18, and raised that to at least 22 over the course of building his legend. In 5E, he quite possibly has a 24. (In 5E, the reason that legendary barbarians can break the 20 cap is likely because Conan is so mighty.)
Welcome to Bounded Accuracy. With a hard limit of +5 in most cases, which is easy to reach and nearly-impossible to exceed, stats really aren't that meaningful in most case. In the game I'm currently playing, my character is a halfling rogue with Strength 10, and he single-handedly knocks down mighty orcs and dragon-people in the process of setting up a sneak attack, because his class features completely overwhelm the normal range of ability modifiers. If you want a game where stats really feel meaningful, then 5E isn't it; even AD&D was better about it, since at least then you had to roll under your stat in order to do something, and rolling under 18 was significantly easier than rolling under 10.The main thing that I have read from those that disagree with my premise is that abilities have so little meaning that they can hardly recall their stats. Let me help you, your primary was a 20. What this means to me is that there are too many feat/ASI bonuses and using them to max out your primary stat has basically become a feat tax. That doesn't sound like fun to me.
