Yeah...I don't agree with this method of thinking, for several reasons:
1) RDM has always been a mage archetype, and only secondarily a weapon-user. So in general it just doesn't fit RDM's identity.
2) RDM in XIV still only has like 4 melee moves (plus a melee-ish Cone AoE), everything else is solidly in a caster role. So functionally it doesn't fit RDM's job fantasy in XIV.
3) RDM in XIV's "unique" niche is defined by its "red magic" spells. While yes this includes the aforementioned melee attacks, this also includes Jolt, Scatter/Impact, Scorch, Resolution, Acceleration, and Magick Barrier. All of which solidly place it in "more" of a caster/healer role than a melee role, and are easily the more distinct part of RDM's kit identity versus the "enchanted slashy slash" that at minimum is also shared by DRK and SAM, if not also PLD, GNB, and perhaps other melee jobs.
4) We are lacking in options for casters as it is. It is clearly *hard* for the devs to come up with casters in XIV that each have a distinct identity when so much offensive magick in FF is elemental-based. RDM shines as a much-needed "blood magic" archetype alongside generic elementalists BLM and SMN. Take that away and casters don't have interesting job fantasies like SGE or AST, unless they want to play BLU.
