I like the idea of a job survey. I'm not sure it needs to be in-game specifically, but something designed to give detailed feedback directly to the devs instead of incessant complaining on the forums and other media would be valuable to have, and not just for battle jobs. The devs could release such surveys for periods of time about pretty much anything from job reality to feelings on issues related to housing or glamour or whatever they're working on. As much as they may read the forums and such, I'm certain there are things they miss, or they don't realize are actual issues to the extent they are unless literally everyone starts complaining about it.
