The Shii Cho Knight talent "Multiple Opponents" gives you a boost dice when fighting multiple opponents yet no change when taking on just one opponent.
However the Makashi Duelist talent "Duelist's Training" gives you a boost die when fighting one opponent BUT a setback die when fighting multiple opponents.
I don't see that a Talent, which is something that gives your characters advantages, should ever have something in it to give you a disadvantage. And why dose the Talent that is the direct opposite of "Duelist's Training" not give you a setback dice for fighting just one opponent?
I think the setback dice in "Duelist's Training" should be taken out all together and just get the boost for going one on one.
