[RPG] Is the eladrin missing racial features

dnd-5eeladrinracial-traitsunearthed-arcana

According to "Unearthed Arcana: Eladrin & Gith", the playable race eladrin doesn't have the racial features Trance and Fey Ancestry like elves do.

I can understand this choice from a game balance perspective, but from a narrative design perspective it doesn't seem to make much sense that a race that is literally from the Feywild does not have fey ancestry!

Is there an explanation for this, or is there something I'm missing?

Best Answer

At your DM’s option, you can select eladrin as the subrace for an elf character, instead of one of the elf subraces in the Player’s Handbook. (same UA article)

Members of a subrace have the traits of the parent race in addition to the traits specified for their subrace. (PHB 17)

The eladrin traits are added to the traits of the base race (elf).
