WOW: Easy Argent Dawn Reputation Revered to Exalted

This yields 250 reputation every minute you work on it about.

Easiest way I found to do it with the repeatable quests. Just do Annals of the Silver Hand (Stratholme one). Fly to Plaguewood Tower and get to Stratholme Dungeon. On your first run kill everything up to where you pick up the book right before the last boss in the living quarter. Run back or hearth to Light's Hope. Turn in and re-pickup but DON'T RESET THE INSTANCE. The book will reappear and you won't have to fight your way to it on the additional runs. Each full loop from and back to the quest giver took around 8 min just running and using the Plaguewood Flight Path.
