Here are some funny quotes from Vanilla racial descriptions:
“Bound to the iron will of the tyrant Lich King, the vast undead armies of the Scourge seek to eradicate all life on Azeroth. Led by the banshee Sylvanas Windrunner, a group of renegades broke away from the Scourge, and freed themselves of the Lich King’s domination. Known by some as the Forsaken, this group fights a constant battle not only to retain their freedom from the Scourge, but also to slaughter those who would hunt them as monsters. With Sylvanas as their banshee queen, the Forsaken have built a dark stronghold beneath the ruins of Lordaeron’s former capital city. This hidden ‘Undercity’ forms a sprawling labyrinth that stretches beneath the haunted woods of the Tirisfal Glades. Though the very land is cursed, the zealous humans of the Scarlet Crusade still cling to their scattered holdings, obsessed with eradicating the undead and retaking their homeland. Convinced that the primitive races of the Horde can help them achieve victory over their enemies, the Forsaken have entered an alliance of convenience. Harboring no true loyalty for their new allies, they will go to any lengths to ensure their dark plans come to fruition. As one of the Forsaken, you must eliminate any who pose a threat to the new order – human, undead, or otherwise."
And the Darkspear description:
The vicious Jungle Trolls, who populate the numerous islands of the South Seas, are renowned for their cruelty and dark mysticism. Barbarous and superstitious, the wily Trolls carry a seething hatred for all other races.
One tribe, however, was forced to overcome its prejudices when it encountered the Orc Warchief, Thrall, and his mighty Horde. The Trolls of the Darkspear tribe, long since exiled from their ancestral lands in Stranglethorn Vale, were nearly destroyed by a band of aquatic Murlocs, but Thrall and the Horde managed to save them. In return the grateful Trolls swore an oath of eternal allegiance to the Horde.
Led by the cunning Shadow Hunter, Vol’jin, the Darkspear Trolls now make their home in Durotar along with their Orcish allies. Their village, named after their fallen tribal elder, Sen’jin, lies along the eastern coast of the harsh, rocky land. The Darkspear tribe also occupies tracks within the nearby jungles of the Echo Isles.
As part of the Horde, the Trolls have extended their loyalty to the mighty Tauren, but they have little trust for the manipulative Forsaken, whom they believe will visit only misery and strife upon their allies.
This is another remainder why Legion intro was awfully painful, for Darkspear to leave reigns of the Horde to screecher. out of all people.
