Biggest Feature not announced yet for Dawntrial

[Rehayem]

Originally it is become Hrothgar Female. But because it doesn't exist they had need to make it Roegadyn.

The majority of Queens were Hrothgars because that's the race that was more common in that land. The last Queen refused use herself as sacrifice for the Save the Queen sword with the Allagans during Fourth Umbral Calamity and some other shrinemaiden from Votyasch tribe sacrificed herself to save Bozja (a Roegadyn)

You're interpreting the post wrong.

SE likely didn't have a female hrothgar in-game model, and probably didn't want to use it in the end even if they did. So of course they made the story like that using an actual female roegadyn instead.

Unlikely they'll alter Bozja's storyline at all even with fem hroth's release come Dawntrail, though. They won't ever touch their previous iterations of content; see Eureka, for example.
