I wasn't clear.
So your issue with orcs is that you consider their current write up as 1 dimensional with the possibility of encouraging racism - which to be fair is basing it off how they are depicted within FG, 5e's setting of choice.
Would the PHB, or if not a playable race, would the MM reflect a number of flipped scripts along with the Standard above? That is what I meant with variants.
How do you imagine it being depicted?
EDIT: Cause you could do the same with the script for elves, less civilised, less magically adept - more cunningly savage, horror of the woods, heavily ritualistic...etc. How does one reflect these variants, separate supplement? in new settings?
Ah, I misunderstood. OK, here's what I would do, if I had actual control over how D&D was presented:
In the MM, I would include 1-2 page write-up for each humanoid species, which included the good, the bad, and the neutral for each of them, making them as three-dimensional as possible in the space allowed. This would include both their player stats, for people who wanted to play them, and a less-complicated mini-template. So, for instance, the orc player statblock would grant Adrenaline Rush, Darkvision, Powerful Build, and Relentless Endurance (or whatever they end up having in this hypothetical edition), while the mini-template would grant +1 HD/+4 hp, +2 Strength and Con, Adrenaline Rush, and Darkvision. (I
would have the standard races in the PHB, but I'd reprint them here in the MM for ease of reference.)
Then I would include a chapter of NPC statblocks, like in the current MM. Guard, noble, bandit, cult fanatic, etc. Only I'd have more of them for all tiers of play. Guards and elite guards, for instance.
Then, if you wanted an orc guard, human noble, elf cult fanatic, or tabaxi bandit, you could stick the mini-template on NPC statblock.
Non-humanoid creatures (beasts, fey, monstrosities, etc.) would get actual statblocks.
I realize that 5e moved away from templates, possibly to make it slightly easier to run straight out of the book without having to do math, but I like templates. Templates that are between 3x's and 5e's in terms of complexity should be fine. OTOH, with the number of people who use D&D Beyond, throwing a template on a statblock could probably be easily automated. And the actual book could contain ideas on how to personalize these templates for important NPCs.
