I really hope this gets reviewed and accepted by Dev.

The only problem in Kensei skills right now is that they're not being used aside the Raijinken and Sharenzan combination. And Sacred Art could get something new running for it. And like Lolzy said, even if you Destiny Kensei, you'll have trouble picking up skills for it without losing one or another major benefit the class gives.

If this gets too annoying to implement, maybe just an increase on the Elemental ATK scalings. (Make Sacred Art use 200% of your Elemental ATK).
