Just thinking way back, who was the one that wanted to make this come to life with Orcs vs humans and the backstory already had with the dark portal.
Who created Sylvanas, Illidan, Maiev, Arthas, Blackhand, Grom, Gul'dan and Orgrim Doomhammer?
Did they just one day say ''Hey, lets mash up a few characters and throw them in an RTS'?
