Eh I'm kinda feeling towards Judge.
I think we're missing one archetype of tank which is Reflective. It could also be proc based on rule cards via gauge mechanic.
I like the idea of giving them a gabranth like weapon. I feel like if it had a Hammer or gavel it'd be way to similar to WAR.
MT stance - Litigation (Double bladed thief sword) Reduces damage dealt and taken. Reflects 10% of damage taken.
OT stance - Prosecution (dual sword) increases damage dealt and Atk speed.
