Hybrid Class: Sword Saint

[NeloAngelo]

I was thinking on suggesting a Sword Saint for a prestige class or base. But since the update on Hybrid Class it seems more..effective? Maybe. But, maybe combine Holy/Dark Knight abilities? Mainly my thoughts was to the sword techs. Maybe add in Thunder Slash/Stock Break/ Crushing Blow etc etc as there's a lot of sword skills that's still usable.

And of course The alignment factor might need to be Neutral? Or A chaotic and/or good requirement.

Thoughts?
