I have not done any number crunching; I only have a sample size of about 5 for each. However, I was wondering what the drop chances for each piece of loot in a given loot pool is. It would be bad if they were all the same and here's why:

Each piece of loot serves one of the following six groups

Bard
Monk
Dragoon
Warrior / Paladin
Black Mage / Summoner
White Mage / Scholar

If each of the 6 types of loot had equal drop chances, this would heavily favor Bard, Monk, Dragoon over the rest.

Does anyone have any better idea about concrete droprates or a counterargument to this claim?
