And what warcraft shows us is interesting? We know that mortal races of Azeroth will win. We also know that any character that is being developed gets plot armor the size of Macragge. Guys that follow their personal agenda at the cost of innocents? Guess what happens to them.

Darkness is, by definition, an absence of light.
