This is a neat idea, I personally wouldn't mind having a healer in the game with a bit more edgelord-factor. And it makes sense since you're bringing people back from the dead... I'd expect them to be a bit lesser on the healing throughput side than WHM or AST, but have enhanced raising abilities. Maybe a single target auto-life like the pomander in PoTD or something. Give them high DPS for a healer to make them useful in farms, but the raising abilities making them good for prog. Seems legit.
