You can't "lock" something that doesn't exist.

Yea, I suspect the Hrothgar are sharing the roe model. Keep in mind that elezen, hyur, miqote, and au ra all share the same skeleton when it comes to gear. They're just modified a bit. Hrothgar is probably using a heavily modified roe model.

If they were a brand new model that would mean SE manually mapped each piece of gear to the new skeleton. I really doubt they did that. :v Insane amount of work to do when they could use a similar model that has all that done already.

Your statement became irrelevant the moment you said heavily modified. If Hrothgar is using a heavily modified roe model, then you could also say that it using a heavily modified Zbrush/Maya/3DS Max human base, or heavily modified cube if thats what they start with. Very few character models start as a cube, and they need a base. If the roe model was used as a base, then fair enough, it makes sense given their size and build, but that doesn't make it any less of a new model.
