I don't get why people want Red Mage it's basically a hybrid that uses already existing magic categories (black/white) and some melee skills similar to the gladiator. Honestly if Red Mage is introduced they will butcher the job like they did with summoner.
in my opinion Blue Mage should be our next Mage job while SE expressed concern about spell hunting it's really not that bad and that's one of the appeals that the ffxi blu had (Spell hunting)
