The Athene leveling method has been blue-approved:

I have tried a slightly modified version of this method (that involved letting the pally tap, but the mage it out of the zone instead) and it works amazingly well.

I've got a heroic geared prot pally and a S2/S3 mage I can do this with and it's insane how much exp per minute it is. If you don't have a mod that tracks that, get one before you do this.
