So when they mentioned casting a song or ninjitsu or magic, they were referencing a bardninjaredmage and not someone in the party? Wooo! RDM/BRD here I come.
Umm what? I had doubts previously but now I'm positive your just trolling people.

Support specialists who excel at transforming their allies from mere mortals into demigods with their enhancements, while rendering once-formidable enemies impotent with enfeebling magic.

We want to see red mages play a more vital role in HNM battles by making enfeebling magic more effective against high-level notorious monsters and their legendary levels of resistance as well as allowing them to better contribute to party member enhancement.
Nothing in there about Bard or Ninja Magic, but hey this is a faulty translation so maybe they've got it hidden in there somehow.

Example Adjustments

Adding abilities that reduce to zero the casting time or recast time for the next spell/ninjutsu/song.
New enfeebling magic spells.
Ohh there it is ... but wait .... didn't they make an announcement for things their adding
Red Mage

Spontaneity (Lv. 95)
Reduces casting time for the next magic spell the target casts.
Ohh there it is, and wow it effects ALL magic, including Bard songs and Ninjitsu.

And for the spells their adding,
Gain-STR (RDM Lv. 93)
Enhances Strength.

Temper (RDM Lv. 95)
Grants the ability to occasionally attack twice.
Not a single other target-able spell there. Not only that, but SE went out of their way to ensure Temper wouldn't work with /SCH accession.

Soo Umm ... unless your idea of a "super party buffer" is a 10 min JA ... then yeah ... your either smoking something, and really need to share it, or your just trolling people, in which case get back under your bridge.
