And what war crimes have the Alliance committed against the Horde?
Internment camps? I find it funny how many consider that to be a crime when you consider the alternatives.
Tried to kill the Belves? Those were Lordaeron troops who're now most likely part of the Forsaken considering what happened after Sylvie reclaimed the city.
And....um....coming up empty here.
And then comes the useless and pointless posturing of "the Horde're better fighters and warriors" especially in the face of the fact that the old rules no longer apply in the face of the Alliance having races like the Draenei (stronger than even Fel Orcs) and Worgen who don't even need weapons. This is balanced by the Horde having goblins, for tech, and belves for magic.
