Given that I just spent the past few days observing the exploiters behavior across zones and among multiple individuals, and clearly seeing the log from the exploiters that their blue mage job leveled up while they were a different class, you're not going to convince me what I repeatedly observed did not occur.

There may be additional exploits being used. One person was shouting the other day that some of the exploiters were going invisible though I didn't observe anyone vanishing and re-appearing myself.
