It reads something like "Guildmasters who leave their position are to be removed of the exp they were given to rank up to SS-Rank." It was ruled as such so that any guild master who left their post would be returned to their previous rank, or whatever rank they may have earned through the experience they gained as a Guildmaster.
But despite many Guild Master's coming and going no one has been held accountable to this, unless they volunteer to be ranked down. Sure the rules mention exceptions can be made in exceptional circumstances, but can we really say that every single ex-gm counts as exceptional circumstances? If everyone is exceptional no one really is.
Heck even Temp Guild Masters have been permitted to keep the exp.
So what do you all think? Axe it or enforce it?
