I don't have issues with both; however, I'm in the odd camp of being pro gender lock short term. I feel that Au'ra weren't made as bestial as they could have been because they thought about the female's design first due to the quote, "players are prioritizing cuteness" (
http://forum.square-enix.com/ffxiv/threads/46936). When a race is female focused it feels it is more confined to a certain mold where males will be played despite more difference between them. Now, they can simply make a new race first focusing on the male design, however, I feel that in the back of their minds they'd be like, "Well this feature wouldn't look good on the female counterpart!"
Think about it, despite not wanting to do Viera in Heavensward was due to wanting something more bestial ("they didn't look beastly enough, they were just a little too cute" Reason for not wanting male Viera). The first character they put out to introduce Au'ra was a cute female, and now the first thing we see of Viera is the female too, which makes sense in this case.

I rather they focus on Hrothgar, if they do exist, as a male race so that they don't have to feel the restrictions about worrying about making a female version that will be popular with the majority of the female character players. That way they can make them as bestial, rugged, hairy and scared as they want them to, and that they don't have to worry about restricting their creative freedom by wanting to make a mass appeal female version which would dumb down the males due to possible complaints about sexual dimorphism.
