@Redhsrike, It is not of gameplay value as the same gameplay can be achieved by rotating this back 45 degrees, normal isometric perspectives, even dimetric and topdown can achieve this.
It's mainly lazyness of programmers methinks, as it is a direct grid, instead of a recalculated, angled grid.
@Andre
Yes the outfits have bended arms, both arms bended equally
The dragon too is completely uniform. Make the stances dynamic and posed, it creates a much more interesting and alive feel, even to a still image.
