In addition it will nearly instantly yank you out of range of a ranged assailant.
Darkflight - 3 Min CD - The Worgen Racial will get you about that same distance over 10 seconds, however during that time you are subject to roots, snares and other immobilizing/speed reduction abilities. In addition if you are fleeing, you will likely remain in range of your enemy for far longer than a "Blink" type ability, giving them ample time to kill you or slow you.
