BLU is just as tied to /NIN as RDM is. Its gearing options are more or less the same, it has essentially the same ACC and ATK, and weaponskills for the most part. While enspells do not work on weaponskills they are very good sources of additional damage. In a straight melee race RDM will trump BLU in terms of damage applied via melee. (although this gap has closed quite a bit since 75 when BLU couldn't cap gear haste, and had no access to (realistic) multi-hit weapons to off hand)

SE has a hard on for hybrid tax, RDM's tax is that because it has no limitation factor on spells and abilities available to it, it is inherently weaker. Unlike SCH BLU and even DNC who can all be solid DD's(nukes/melee combination of both), Healers, but more or less lock themselves into one role or the other, (DNC burns TP to heal, SCH married to Arts, and BLU limited in spells it can set) A RDM can cast its spells whenever, wherever.

As my good buddy Tanaka would say: BALANCE!!!

Thus the only way RDM will ever be a strong (comparable full time) DD, Nuker, Healer is if SE restricted other aspects of the job when we are performing a specific action. Personally I have no issue with shutting down my melee side to be a better caster, and vice versa. But that still doesn't solve the issue with RDM not being invited at all. If you want a DD you get a DD, a Healer a Healer, a Nuker a Nuker.

To be a broken record, the only realistic place for a RDM to be buffed (aka fixed) to get a party spot is Support Mage, meaning enfeebling and enhancing skills and spells need to be fixed, to set RDM apart from the rest of the buffer/debuffer mages. Binary casting is very 2004, especially with 3-4 jobs all being relatively the same, there needs to be some way to be distinctive. WHM has healing and divinemagic, BLM has Elemental and Dark magic, RDM should get support magics, enfeebling and enhancing.
