Shinten/Kyuten should upgrade into Senei/Guren. Lose the CD. Make it pure Kenki Spender. Since you only spend Kenki on 4 skills? 2 of which share a CD and have a 2min recast. Trash.

Shinten is pretty garbage right now and is only used when you will overcap or dump it with 3 Shinten/Kyuten before you do your Senei/Guren.
