There have been instances where I thought "gee I would really like to play X exclusive job but if somebody else rolls that I'd rather play X latejoin job" and I think this would neatly make that possible. For example, sometimes I want to play as the clown first and foremost with the mime as my "second best" choice. However, I'm generally unlikely to be a clown if I latejoin so I have to choose between trying to roll for the clown or holding out to be able to play maybe both but most likely just mime.

I can also see in an RP-sense how someone could potentially have a character who is specifically a job/in a department, and they might want to only play that character if they can play that job. (Maybe it would be weird if someone's doctor character was an assistant). This change would let people change to a different character in a situation like that.
