As far as RDM goes, I am hoping for a melee support. I feel like that would be the best way to capture the "do it all, master none" theme of RDM. Let them buff, let them debuff, provide a decent amount of damage, and give them a sort of heal that works more as a HoT. Rapier seems like a given, but we could go the extra bit and give them a offhand as well. All of those shields THM and WHM use to have could be restated to RDM and given a point again. Maybe we can do something amazing and let them switch their damage from physical to magical, and whether you use a wand or sword would be completely optional. Not one better than the other, but the same stats. It would be an illusion of choice that wouldn't demand you have one or the other. I'd even go as far as to find a way to let them glamor over each other.
