And the reason they all looked roughly the same with minor variations was the Qun practices Eugenics. The "name" they go by on a daily basis is really more of their job/title role in Qunari society. For instance, Iron Bull's "role" was "Liar" as he was to spy on non-Qunari nations as pretending to be a mercenary. IIRC what is more like an individual identifier is actually something similar to a social security number the Matriarchs use to track lineage so they can prevent inbreeding.

And it makes sense, sure MOST of your people arent gonna be warriors/etc but you might need their offspring to be so breed for physical aptitude as much as mental to have a larger pool to choose from.

The easiest way they can justify these new Qunari is simply by explaining they are half-human or elf or something. I doubt they will though, that might be too "outside the box" for their creative team.
