Gender locked race?

If Hrothgar are added, I wonder if they'll have any speech quirks like the Ronso?

I'd be fine with that. One thing I like about FFXIV is the accents and/or speech quirks they try to give characters, beastmen included (when/if they get a voice). Gives the world a little more flavour.
As much as I hate Viera, I do hope that if they get any voiced lines, they have the same accent they had in FFXII and not just be England - Forest.
