I think giving red mage a rez lock makes them worse than SMN for progression.

I currently think RDM is fine, buff it’s damage a bit and give it more defensive utility to really nail home the prog King status, MP/TP Refresh preferably as one skill, and maybe an AoE Shield to help mitigate damage. Casters are already balanced well amongst each other, SMN seems to be powercreeping RDM in prog though so I’d say buff them to prevent that from happening.
