Going to point you to exactly what Blizzard added into WC3 and the NPCs name as to why this is irrelevant:
They’re satyrs in this universe. Why use any of the other terms? Your logic makes no sense. Female satyr have existed as part of the lore for quite a long time now, not represented in game until WC3, but a female satyr has a male satyr body in Legion.
There’s nothing to nitpick here. Satyr are both genders in Warcraft lore. Period. End of story.
