Paladin
-Requiscat is moved to Magical Damage
-Shield Oath generates gauge on being hit instead of on blocking.
-Sword oath generates gauge on weaponskill usage instead of Auto Attacks.

A small nerf on Paladin's damage, a nerf on Sword Oath gauge generation, a gain on paladin's Shield Oath generation.

Dark Knight
-TBN no longer costs MP. When self cast, it uses up to 25 Blood and refunds twice the amount it took when the shield breaks.
-Sole Survivor grants ramping Damage Reduction based on how many enemies were nearby upon activation. Killing a nearby enemy extends the duration.
-Power Slash adds half its potency to the next damaging Spell or Magic Ability utilized.
-Souleater instead grants 5 Blood. Siphon Strike and Spinning Slash now grant 5 blood.

Dark Knight's dynamic with TBN and MP is removed. TBN remains best utilized on Tank Busters and the 'risk/reward' mechanic is now solely for blood. Straight up Buff.
Sole Survivor is made useful to fill the mitigation hole in Dark Knight's kit.
Power Slash is given another pay off to minimize bad feelings for having to use your Threat Combo. Most effectively utilized with Salted Earth or Dark Passenger
Blood redistribution to not so heavily stack Souleater's combo line.
