I don't see what you are complaining about. A couple days ago we had a new player get their first job to 50. Last night we took her into Ifrit, Garuda, and Titan for wins and she got the weapon from all 3 ... and NONE were for her current job.

Oh yeah ... one difference is since we wanted her to get the weapons for other jobs, we formed a full party and everyone passed to her

Try it! It might actually work.
