I am not sure tbh.
Having mained blm for years the simplicity of Red Mage is relaxing, lol
However i do think it needs to be more complex and move away from the role as just a "progression" dps, there is no reason why it could not be made more complex and do more damage.
Changes of course would need to be made to embolden and veraise but more spells/attacks would be very welcome along with more options for aoe. Enchanted moulinet and scatter is meh.
I would also love to have more spells/attacks and not dots (that belongs to smn) but perhaps something that adds status ailments like some that cause slow, etc...
Of course just adding more spells/attacks does not necesarily make a job more complex
