well i plan to atleast take every craft to max. while lvling all tank/melee job to 40 then maybe go to magic one's. if your going to play a game might as well take it to the fullest.
my advice, level both mage jobs to 16 to get the usage of their support abilities. Conjurer gets cure at 6 and stoneskin at 8 and thurmatage gets sacrifice at 6 and stygian spikes at 16. They will be SUPER usefull when you level your melee jobs.
EDIT - maybe take it as far as 21 to get prot/ shell
