If you have a level 80 friend that is willing to help you level this is a great method to level from 75-80. First you get the quest The Amphitheater of Anguish: Yggdras! - Quest - World of Warcraft and summon the mob. Tag the mob then have the level 80 help you kill it (make sure your friend is outside the group). Abandon the quest now and re summon the mob. Me on my shaman and my friend on his boomkin were getting me 600k/exp an hour. I'm sure it would be even faster with a ret pally.
