With the introduction of crane hop, people began to use Kensei's autohit skills more often. As a result, we realized that Sharenzan was absolutely decimating everything it hits. Full tanks would Raijinkened for 10, then sacred art Sharenzaned for over a hundred damage and a knockdown. The poor souls who weren't tanks found themselves taking over 200 damage from just the second hit. Additionally, the simple (yet backbreaking) combination of crane hop Sharenzan puts out simply too much damage. Kensei is not in a great spot in terms of damage compared to its counterpart, Ghost, but concentrating pure death into this autohit is not the way to change that.
