I agree with what both Spoops and Shujin have said as I've stopped using all kensei offensives since the GR. But, I also think Sacred Art needs to be looked at, too.
The elemental damage gets reduced by RES, magic armor, and elemental resistance (correct me if I'm wrong), so the whole elemental ATK damage becomes pretty mediocre. If it could just become irresistible like matador's retaliate, that would be a nice start. In comparison to boxer, the damage still doesn't even come close with this change.
