Thanks for all the replies guys.
I think I should perhaps mention that, while, Thief & White Mage is what we are leveling now, its only because our options are staggeringly limited without advanced jobs. My wife might stay with White Mage, but has shown interest in leveling Summoner or Scholar instead. As for myself, I have no interest in capping Thief, and will likely jump ship the moment Blue Mage or perhaps Beastmaster becomes available to me. Felt like that was a detail I should have mentioned before @_@
