I want to stop pretending that a character’s ability scores dictate characters’ physique in any meaningful way. A Goliath with 10 strength (or even as low as 5 strength if you roll stats!) can still be 7’10” and 440 pounds, while a 2’9”, 37 pound halfling can have 20 strength. And both characters have the same carrying capacity (300 pounds). And the halfling will deal significantly more damage with melee weapons, but the Goliath can be a significantly better archer, I guess? Ability scores have never translated into physical characteristics in a way that has made any sense, and the game has consistently improved as the attempts to pretend they do have gotten relaxed. Again I say, the sooner we can just stop pretending the stats mean anything more than what they actually do, the better.
It has only ever meant that, and the game would be better if we would stop trying to make it mean more.
