Hey guys, a few of my guildies and I have found an xp exploit for the Aldmeri Dominion at ~level 10.
It involves two bosses in the ruin called Ezduiin on the isle of Auridon.
you must do all of the quests up to and including whatever quest brings you to the ruin. (I believe it's mages guild but could be wrong)
you must go into Ezduiin and then turn right at the bottom of the first set of stairs so yo are in 'Ezduiin Inner Sanctum/Undercroft'.
There are two bosses standing facing one another, I think one is named THundermaul.
They both have respawn timers of ~15 seconds and grant about 100xp together. Used this until level 16.
Good luck and have fun
