Interesting thread. There have been numerous RDM idea threads since the ARR release (and I'm sure since 1.0, though I didn't look that far back), so in some ways this concept is no different from the others. Very flushed out though, so props for that, but I'd still love to see it as a melee class with some magic (a bit like how NIN looks).

I'd throw in Red Lotus Blade and Death Blossom for weapon attacks, and Refresh, Slow, Gravity, Haste, and Paralyze in their spell lineup, in addition to some En-spells (instead of the "pulses" you envision). Obviously, this is probably too much for a job to have, and many of these would have to be in the base class (which I could envision sharing with Blue Mage - with RDM specializing in debuffs and En-spells, and BLU focusing on monster abilities).

I do like CNJ as the prereq, and think it fits very well with RDM as a potential buffer in addition to being a DPS class.
