If they at least could take into account which classes are in the party that would be a big step in the right direction, For example in my group we have seen more then a few MNK items drop, problem is that we do not have a MNK in the party. To add to this, from BCoB, SCoB and FCoB we have never seen a caster chest drop ever.
If my memory does not fail me I am pretty sure they said something about changing the loot system for the expansion.
