There has been a bit of progress on the aforementioned sanction adjustments that I would like to update you all on.
Currently it is only possible to receive sanction from the Grand Company counter you are a part of, but in patch 1.22b we will be making it possible to receive the effects of sanction from the other Grand Company counters that you do not belong to after completing a special quest.
We are still continuing to look into items that will imbue you with the effects of sanction and will be sure to let you know of any updates on that front as well.
