It was more of a rhetorical question. I've been playing D&D for over 25 years now. 
I figure that is what makes this game really nice. For body types, different strokes for different folks.
*Too dense to notice rhetorical questions* 
That's what I like about it, too. While the body models aren't perfect, it's at least better than using a standard model for every race/gender and not offering a body slider.
So to the OP, if it bothers you, I guess you could play as a human/qunari/dwarf? Or you could use armor that gives some bulk to your Inquisitor's arms. The robes used in the demo made the arms look even smaller with how thick the smock was around the PC's middle, so I assume using more body type-flattering armors/robes would help to cover that up, if you were thirsty for that elf play through.
