We are talking about brute force, sheer strenght and not magical one. And therfore Belves will be always behind Kalimdor races in this regard. Unless you really think Belfie can take female orc in arm wrestling.
I just find big bulky characters as more convincing as warriors. That this character can really take a hit and not snap in half, that can carry heavy armor and fight bigger foes, and not complain that she broke her nail.
But that is just my opinion and how I see it. I'm not there to tell people on what they should play.
