This is the same method i used to farm Time Lost a couple of years ago. Sat 4 toons on the spawn points and had my 5th account sitting in Ironforge playing the AH.

I killed Vyragosa 52 times before i had Time Lost spawn infront of me. Funny thing was all my toons looked exactly the same and had almost the exact same names so id watch this pally fly past one spawn point then get to the next and hed msg me "WTF HOW DO YOU GET TO THESE SPAWNS SO FAST !!!!"
