I've noticed that the vast majority of beings who are connected with Death seem to always use Shadow magic, look at the nathrezim, or the NPCs in some of the realms of Death, or the dark rangers, and even most of Sylvanas's abilities. Even the very name of the afterlife implies that Death is far more closely associated with the Void than the other cosmic powers. The Void regards Death as its enemy, but for example, the Forsaken and nathrezim always seem to use Void powers without much hesitation, and there seem to be a far greater number of them who use the Void rather than the Light. Why is this so? Isn't this somewhat contradictory?

(Of course, this could be because of obvious game mechanics limitations, but it is still interesting to ponder.)
