Well, don't be blind for one, hah. But it's not hard to make a fairly effective character. I'm thinking of playing a Shinjo Bushi, however, I have another idea I'd like to clear with the GM first. Would you allow a Taoist Swordsman, from the Emerald Empire, to take the Friend of the Brotherhood advantage, even though they are bushi but described almost as monks? If so, I'd very much like to play one, and might play one anyway.
Another idea, though, is would you allow people to play a 'ronin' but using the Boar School, taught by some distant relative to the long dead Boar Clan who still continues to pass along the techniques. Juggling all the ideas right now.
However, in Enemies of the Empire, there are many more schools for later on as well.
