Red Mage "better"??

[OneTrueMiqote]

Your auto-attack damage as RDM isn't nearly potent enough (and is hardly fast enough for that matter) to make that a necessity, and Embolden is both predictable enough to reposition yourself before the cast and, thanks to Manafication, frequently lined up with your melee phase anyway.

The reason to why you stack with the group is for heals, buffs, and mechanics. And since melees and tanks need to be melee range, naturally the party would be in melee range too.

The obvious intent of the kit, as demonstrated by multiple NPCs

Or maybe how the job is played should be demonstrated by skilled players and not NPCs.
