You realize that the developers are actually trying to do the opposite of this right? That's why they changed all the daggers low level paladin/gladiator's got into swords when rogues/ninja were put in. Also why they are now going through and removing the wands and brands that low level white and black mages had to deal with and changing them to staffs and rods. They want each job to have a relatively unique type of weapon with the only exception being SCH/SMN because they come from the same base class. (which they have said was a major mistake anyway.)
