I'll have to look up the link to this particular response, but their response to PUP getting mage gear was along the lines of: "PUP is a job that wears light cloth armor, so that is the type of stuff that PUP is able to equip."
What this says to me is that the actual stats on various armor types are not the determining factor regarding whether or not a job can wear them. But rather, how a specific armor type (cloth, leather, heavy plate, etc) fits into the lore of the job.
