Then why pick a Qunari? Roll of the dice? 
I was originally intending to play a female elf, but one day I just decided to go qunari instead. Because I thought it would be interesting, and it was a striking look.
As it turned out, it made it every interesting - how people responded to her was different to how it would've been with other races (obv, yeah) and it really leant itself to the whole "yeah, I'm not who you think I am, and I'm just making this all up as I go because, well, it just seems right to me" thing that she did.
That's Marchers for you.
As a bonus, I had no idea in advance how much a certain lady with lots of arrows at her disposal liked that kind of thing 
A race that offers nothing in and of itself except looks.
I am curious as to exactly what you feel the different races need to offer to justify them as choices? I mean, there's always going to be a limit to how much a game can react to that choice, and I personally feel they did a fair to good job. But then, I do have only one Inky...
