This is one thing I will never use in my campaign as it goes against everything I have ever believed about L5R. Having an artisan make jokes about samurai at court, just doesn't fit for me. It is too "medieval fantasy setting" for me and with the social stratifications, I cannot see it happening in my campaign.
I know that there are many jibes and slights that are all part of the maneuvering at court, but I thought adding a Jester was just too much for me. Many people may like it and that is fine, great having options in all games.
