So..Lets talk jobs?

Since we want a melee RDM so bad, they could make RDM a melee attacker/debuff by giving them aoe saber/en-element spells that can applied to all melee attackers. These spells could give each attack a slight elemental bonus, absorb hp/mp, or have a chance to enfeeble, etc. Each individual attack isn't as strong as a cure spell or nuke, but cast on enough people the numbers could add up. In terms of party dynamics the RDM would not be as good as a regular attacker in terms of dps, but they bring to the table some decent buff/debuffs that could play nicely with BLM and WHM spells.

Gotta be careful when balancing those numbers. Experience has taught me the numbers have to still be decent and not significantly behind the other front-liners, because if people figure out ways to getting that same damage without the RDM in the party, you're kind of boned and back at square 1.
