Loot lockouts should be based on Job

[DoctorPepper]

I'd be fine with this, if they made it so that you can only need on gear and you can't greed things for your other job. Or,

Let's say you are tanking as pld and drg gear drops and you greed it. And later you get some tank gear. Both your drg and your pld should now be loot locked to that instance of BCB. My point is you shouldn't be able to roll greed on gear on one job and then greed the same gear on another job. If you could FC's could abuse the system immensely.

I'm not sure if you misunderstood me or not but this system would effect greed rolls of course. If you are a pld and you greed roll a piece of drg gear then you are locked out of drg gear until the reset. Same goes if you're a pld and need roll pld gear, you're locked out of pld gear until reset. In the examples you give you're assuming that greed rolls would not lock you out, that isn't what I'm proposing at all since I completely agree that would be very broken.

Edit: Your post also brings me to good point that is specifically for coil, right now it's entirely possible that you could get very lucky and obtain 5+ drops from a single set of coil runs. The system I'm proposing would remove the chance for that to happen (unless all items are for different jobs), thereby in some cases, extending the duration of the content would last.
