Feedback:User/Phlemhacker/Char physique

I was noticing in the artwork and the trailer for Guild Wars 2 that the Char seem to be more upright than they were in Guild Wars. I was wondering if there is and explanation for this. It's been bugging me since I noticed it.

Suggestion: 250 years isn't long enough to evolve but perhaps some sort of virus or condition magical or not caused them to change.
