Best 4 person all caster/priest group

[fortior]

You want rezzes, you want paci, you want ports, and you want dps. Shamans add literally nothing to a group that's that stacked with pure dungeon crashing power. It's a class for people who want to solo the same way in every situation, and if their one trick doesn't work they can't do the camp. Shaman is the class you bring to a group when you're carrying melees.
