Looks like they're going to redo Shoha's mechanic for 5.1.

Hagakaure was removed because they thought it complicated the rotation too much. I don't think the devs played the same class we do. Hagakaure was key in keeping the rotation smooth no matter what skill speed tier you were at.

Ninja is going to be focused on first for like 5.08, so don't expect any Sam changes for a while.
