A random idea for dishonored dojo, maybe it can kickstart a few better ideas:
Dojo Disgrace and Dishonor
Dojos (and gangs) can only provide their full training benefits as long as they are not disgraced or dishonored, meaning that they have no negative record.
A dojo with a negative record is either disgraced or dishonored, depending on the number of styles taught:
For each point of negative record, the teacher must choose two of his taught styles. These styles are not available for new students (but old students learning these styles are not affected). As long as the dojo teaches at least one style this way, it is disgraced. If it loses access to all styles it can teach, it is dishonored, and cannot accept new students.
