Does the concept of subspecies of Elves come across as racist to you?
This question comes from the
Half-Race Apperception Thread
Nope. The term isn't great, though, and doesn't necessarily/hopefully match what they're doing. (see end of the post)
Not in the least, because it isnt.
In before the lock.
Agreed.
All elves share the same traits for age, size, speed, Darkvision, Trance and Fey Ancestry. The only traits that do differ are cultural traits.
I quoted this before seeing that you replied to someone whose posts I can't see who apparently pointed out that this isn't true in actual DnD. Still quoting it to say, this is partly true about them all having some traits in common, and that's important as I'll explain at the end of the post.
In Level Up, Culture as a rules concept does exist. But you are right, it doesn't exist in 5e or One D&D.
Yeah and people keep trying to make background into that, and just no. If 5e ever adopts culture as such, it needs to add it, not replace backgrounds which speak to how you grew up or what you do or what was your catalyst to become an adventurer.
However, One D&D is 5e. I point that out not to be pedantic, but because part of why I'm confident in how species will work in the PHB after next year is that we've seen a preview in Monsters of The Multiverse, and the relevant bits have been carried over into the PHB UA so far, but not in a super clear way.
So, in answer to the OP, again, no, but "subspecies" isn't a great term for it. Instead, there are either multiple species of Elf if they work in the style of the MoTM elves like Shadar-Kai and Eladrin, or they are each a lineage of elves, which in a modern sense would still use language like "drow and wood elf are two species of elf".
Personally, I'd prefer them to go with the MoTM model completely for elves, dwarves, gnomes, etc, but for dragonborn or goliaths where it is just who your specific draconic ancestor is just use the UA model.
