Heck since game release I would have never minded if you could only roll on gear for the class/job you are currently playing. As it stands now, just run it however many times per week you can stand, and when you only have 1 or 2 more runs left in you just greed everything until you get SOME drop so the week is not wasted. Save it for an alt you already have or will have. Then, you no longer have to get any lesser level 50 gear for that one job for that one gear slot.
