So where is the Iksar Betrayer spawn now?

Get some friends and drop down into the slave pit between AOE pulls. Kill the static spawn and set a 20 minute timer. Pull mobs from tunnel one at a time. Pull roamers since those are the PH. Keep this up for a few cycles and the mobs will spawn on your timer instead of the AOErs. We did it with a 58 monk / 58 shaman on a Saturday morning and it took 1 hour
