Bring Back Kaiten

[TheDustyOne]

You can best compare it to Dark knight, DRk actually has a choice here, does he want to spend 3000 MP for one more attack but cant use his shield or is it better to keep MP?
Kaiten was a "must always use" situation, just stay above 20 kenki, use Shinten only at 45+.

Terrible example, it's the same choice. "Do I spend 3k MP on Edge and risk not having enough for TBN when it's needed" vs "Do I spend 25 Kenki on Shinten and risk not having enough for Kaiten when it's needed". Even in your example of "just stay above 20" is the same as DRK, just stay above 3k MP.
