Judge Magister as a Job. Just copy Dissida Gabranth. Starts out as a twinblade then once your gauge is full enter EX mode and dual wield, similar to DRG LoD gauge but you can actually prevent it from dropping. Also, plays like SAM's sens, where you do your rotations but instead, build Quickenings then use it for various high potency spells, i.e. Pyroclasm, Maelstorm's Bolt, etc. Boom you got yourself a new job.

Originally I was thinking this could be the new maiming job back in SB but since reaper filled that role, making it a tank could push more people to play tank. Especially if it feels like a dps, similar to how GNB, plays.
