Oh god no please.... This is why I'm glad you people don't work for the Dev teams..
Make Horologist (Clock maker) Time Mage's class.
and Make like Fencer or whatever cool word SE pulls out of time air to be Red Mages class.
This way they both have their iconic AF...
And everyone is all up on Red Mage for it's En-spells from XI however wouldn't you rather have it specialize in Dual Cast (Casting two spells at the same time) a Traditional Red Mage ability and unique spells to it's class. (Leave Time Magic to a Time Mage and En-spells to a Spellblade/Mystic Knight)

See Red Mages are just greedy I'm starting to think, they want to steal Time Magic and prevent Time Mage from being a Job, and they want to steal Enspells and prevent Mystic Knight from being a Job, get over it Red Mages, just because in XI to try to give it SOMETHING SE gave it other job's things doesn't mean that's how a real Red Mage is. (Using Single Target White and Black Magic, With Dual Cast, and a Rapier/Foil) and I'm sure SE could add some unique niches that would make it decent at melee and give it some of it's own unique spells, but don't future Red Mage community don't have SE be lazy and hi-jack the spell lists of two possible jobs.
