Culling and restructuring skills to make room for 5.0 abilities

[Seraphor]

"- Add a Fourth Mudra"

Um... this alone would require adding SIX new abilities:
X, 4
X, X, 4
X, X, X, 4
X, X, X, 1
X, X, X, 2
X, X, X, 3

Which would be a pretty convoluted addition, screw over controller users (because the three mudra and ninjutsu fit so well on one pad) and I'm not sure what you could use as the fourth mudra with Tenchijin being pretty well defined.

Unless there is just ONE more skill, that's accessed by using any four mudras, not needing to actually create a fourth mudra as such.
