It is past due for another caster type DPS jobs, and it could probably work, but probably not as you think. For example: SCH in FFXI is very different then SCH in FFXIV, if they did introduce time mage, it probably won't work like you think, Much like people wanting red mage so badly even tho it won't follow the same style as it did in 11, it's just because it's "red mage" that people want it.
