Don't dismiss it right away. Please read fully and have an open mind please.

I had an idea of a Disciple of Magic tank. Maybe a Spellsword type of class. It could be an okay idea. If they did it right, that would be a class/job I would be more than willing to try.

I was thinking you could have a spell that enchants the user and his/her weapon raising HP. This spell could be similar to Defiance by reducing Intelligence. Attacking could draw off of intelligence. It could generate AoE aggro with defensive self shields in addition to basic attacks and rotations. Maybe a Circle of Scorn style spell. Brief defensive cool downs to reduce damage taken at a pacification cost.

Maybe make it a Thaumaturge job, so it could draw Fire and Blizzard for more damaging spells. It could have different versions of the Defiance type spell to be like Monks fist forms. Fire enchant for more damage, Earth for higher HP, and Wind for more spell speed.

Just an idea. What are your thoughts? Any other ideas for any other classes?
