One of the Dailies on Tol Barad Peninsula is 'The Forgotten' where you have to release the spirits of 6 tortured souls on Forgotten Hill.
Discovered by accident and worked on 3 separate occasions on 3 separate toons - as soon as you click the tombstone immediately after cast a long heal (have not tried with anything else) and the spirit will not spawn, saving you heaps of time and making that daily a lot quicker.
