Permissions could be fixed to disallow individuals to adjust their own ranks, it's also true that people with a rank which has been given the ability to promote should be considered trusted before earning that rank. Some people are failing to realize that this isn't a matter of blaming people for stealing or bad management of current permissions, but that the current permissions could be improved.

I would like to see expanded permissions so functionality is much greater than currently set. Like, a setting for people to withdrawal up to a certain amount of money or a certain amount of items per bank slot per day.

I was robbed shortly after I first started a FC, but the only thing of consequence at that time was materia. Currently, with strict permissions, there are no robberies however the FC Chest functions more like a display case rather than something to be used as a central repository for everyone to benefit from.
