Armor of Hope: Req: Armor of Light. Level 11
You may use your Armor of Light to protect you from certain doom. When you would be brought to 0 health by an attack, you may expend your armor of light to only fall to 1 health. On the following turn, you may recall your Armor of Light as usual.
As written this seems open to abuse, and you could essentially avoid a killing blow every other round.

If I drop the Proficiency to Medium, and add the armor of light feature, remove the hunter's mark from the expanded spell list from the Justice Arche Type and Clarify that Versatile Swings does not make the weapon eligible for any other benefit of using a 2 handed weapon all move the class in the right direction?
