As a DPS i used to hate when a healer is dead and the other healer is struggling to keep us all alive and never bothers to raise him. Just raise the dead healer and it's SO much easier to recover. 1 healer in a hard fight is just a slow domino effect, unless overgeared, you cannot solo heal something like Ravana EX, it's very hard. Cap tank off with Adlo/E4E/Sacred and start casting raise.
