Hrothgar are a niche race, so it makes sense for SE to make sure the females make sense with the race (as bestial as males). It doesn't make sense to me to just make them Miqo'te 2.0 (or Roegadyn 2.0, if people keep bringing that "Rule 63 Kimahri" fanart up).

Whether it'll be popular or not is irrelevant, as there is a market for the more bestial appearance (present in this very thread).
