so basically what you are saying is, in the situation of dnd, there is no real reason races couldn't have similar stats, since its fantasy, a game, and represents a reality we are unfamiliar with. Chimpanzees for example are 1.35 times stronger than humans on average. average height 3 ft 3.
so really it just comes down to either liking to have race controlling stats or not, and logic/realism really having nothing to do with it.
Which is fair as an opinion, but its not the only way to do things.
the new system in my opinion is superior because
1)its a more flexible creation system in a game. 2)it allows your table/players to either follow the norms or not, as they wish and can conform to either preference. GM could easily tie certain backgrounds to certain races. 3)its likely more balanced
the old system generally made players either totally ignore the race aspect for those who don't min max, or to Tailor the race to fit the utility of the charachter, not the story or desire of the player.
