What's the symmetry of Human-Orc?
Well, the obvious first comparison was tribal societies vs town based societies but...
That's culture with in not assumed.

Okay, fine, you want a different angle. How about the adaptability and versatility of humans (mechanically represented) against the unstoppable, unyielding toughness of the orcs (mechanically represented).
Don't like that?
Humans are the race most commonly found to have nobility and lines of succession, orcs tend to have rule based on might makes right and sacred ceremonies.
Another? I could, but again, the point is you CAN find these things if you look for them. So, how about this, Other than "culture doesn't count" what reasons do you have that these cannot possibly be contrasted?
What's the symmetry of Dwarf-Elf?
Um... two of the most common fantasy races of all time?
Yes really.
These arent the Anti-magic Dwarfs of the past.
This isn't Warhammer or 1e.
Try again.
Who needs to be Anti-magic? You have Forest vs Mountain, Wood and Nature vs Forge and Steel, Tall lithe and beautiful vs rough short and stocky, Sword and Bow vs Axe and Hammer.
It is Elf vs Dwarf. Literally one of the most common fantasy opposites in the entire genre of fantasy. Again, other than "Culture doesn't count anymore because WoTC bad" what objections do you have to state that Elf Vs Dwarf cannot possibly be a contrasted pair?
