I think I'd be more on-board with the Syphon Strike, Souleater, Living Dead, and possibly Plunge changes if it also nixed Plunge's ridiculous animation lock. I have no idea how Shoulder Tackle and Onslaught continue to be quick as hell and 20 yalms while Plunge is so clunky.
I think it'd be cool for Carve and Spit to really be a "threefold" attack like Dream Within a Dream, as it would give more blood and MP under blood weapon. A small little buff consideration.
But the rest to me either feels too similar to Warrior, a bit too powerful, or both.

Knockback protection...I'm not sure why something like that couldn't be tied to Awareness or something instead of Paladin getting it for free.
