Yes, the machanics can be pretty deadly, which is one of the things I like about it.
Mind you, our primary warrior-type is a Crane trained as a dragon, who also has reflexes 4, so she doesn't get hit a lot. The other is a miromoto bushi who's a tad uncertain about his skill with a sword, but really likes books.
Nice team, actually. I'm expecting a kakita bushi later, but not for a few months I think.
