So I came up with this idea talking with someone in another thread. But do you think Shoha would be better if... (Sorry if someone else has had this idea already.)

They turned Shoha into a WS that had it's own CD timer.
Made it increase in power for every SEN you eat with Hagakure.
3 SENs would cause it to do more damage than one Midare.

This way Shoha becomes a nice lvl 80 ability to have and Hagakure becomes more useful than something you only use in between trash pulls in dungeons and boss phase transistions.
