Actually ... RDM's "end game" value in the past was .... drum roll please ...

Cure IV
Erase
-na
Haste
Refresh

With the situational use of our trademark Chain Spell Stun during zergs.

Enfeebles were a joke at 75, nearly every HNM was super resistant if not flatly immune. The ones they did land on had built in potency reduction. RDM was used' as a miniature white mage that could also nuke, haste, self-refresh and had lots of MP. Since they've bluntly said their not giving us Cure V we can rule out the miniature White Mage use which leaves players in an unfamiliar position. When a job was abused and pigeon holed as a WHM-1 for so long that people actually began to think that is what it was designed for, what do you do when it's no longer viable in that use? We've always had alternate functions, but so few people properly explored them that their considered fringe only.
