Err...
Draenei are Shamans because Velen had a vision and told everyone.
You phail
VISION:In recent years, Velen, the noble leader of the draenei, was granted a vision.... In it he saw the Broken: formerly healthy draenei who had devolved during the orcs' murderous crusade to wipe out the draenei race. According to Velen's vision, the Broken would rise to power once again and aid their displaced brethren.
Velen's vision was given substance in the form of Nobundo, a one-time draenei priest who had devolved while the orcs decimated his race and tore the planet apart. Like his fellow Broken, Nobundo had lost contact with the Light, and so he ventured far into the deserts of Outland to meditate and pray for guidance.
After decades of silence, an unfamiliar voice finally answered his prayers. It was not the Light that whispered to him, but the wind. The breeze spoke to him of lost truths, of the might of the elements – of the delicate balance of power embraced by the shaman.
Nobundo listened eagerly and learned all he could. When he judged the time was right, he departed the desert determined to use this knowledge to help the draenei race. However, most draenei refugees greeted the sight of a Broken with skepticism and outright prejudice. Only one of the healthy draenei did not shun the Broken: the wise and perceptive Velen.
Velen had heard the philosophy of the shaman before, but Nobundo revealed new truths. The elements were timeless; they stretched across the cosmos to inhabit every world they touched. With the proper training, the draenei might learn to wield this overlooked, seemingly inexhaustible source of power. Velen rejoiced to realize that his vision was coming to pass. Accordingly he took Nobundo with him when he and his fellow refugees took possession of the naaru satellite structure Exodar from the blood elves. Thus it was that Nobundo journeyed with the draenei to the world of Azeroth.
Nobundo found that unlike the desolate wastes of Outland, Azeroth possessed abundant elemental energies. He shared his knowledge of shamanism with the draenei on Azeroth, and all who adopted its path flourished.
The time for the draenei shaman to test themselves draws near, for the battle against the Burning Legion is once again at hand. And the fate not only of Azeroth, but of all worlds, hangs in the balance.
IT Was Nobundo who taught the Draenie the power of Shamanism.
