What if they only awarded the 5th chest if there are no duplicate jobs/classes?
(and disallowed job/class changing while in the instance)

At most you could have 1 job and its nearest class, i.e. 1 Black Mage and 1 Thaumaturge since we will probably need 8 people and there are only 7 jobs and 7 classes... but any duplication negates the possibility of getting the 5th chest.

Or maybe give a bonus for having no duplicates? ... like a slightly higher drop rate?
