Dancer - Blue Mage, how they could be done interestingly

[Selvokaz]

Dancer: The close range healer job.

Dance focuses two stances, Freestyle and Fundamental,

Fundamental, dance steps used while in fundamental would work like most healing jobs, in that they can heal a target from any range within their range of the spell, and have the same cast time as such a caster would normally have. In this case they are very vanilla. The benefit of Fundamental however is that you regenerate MP and TP much more quickly (1% per second). Think of it as the cooldown phase of a dancing routine.

Freestyle, is where things get a little funky. While in freestyle the dancers casting time drastically decreases for both her healing and her offensive spells/skills, she also doesn't regen mp or tp, her healing spells heal more, and her offensive weapon skills hit harder.
Freestyle also builds up a gauge called fatigue, when fatigue reaches 100% your automatically drop out of freestyle and back into fundamentals.

Skills and or Spells used in either style carry additional effects based on the style. While in Fundamental style any spell or weapon skill used regenerates MP and TP for you the caster. On the flip side any Spell or Weapon Skill used in Freestyle builds the fatigue gauge more quickly. For the sake of the post any spell or weapon skill fills the gauge by 10%, also note that being in freestyle builds the gauge automatically by 1% per second.

Weapon Skills: The Dancer has 4 different dance steps that count as her weapon skills, The Jig, Two Step, The Spin, The Slide, these all have a range of 0 or melee range, they attack the enemy and expend TP, while in freestyle their potency increases by 30, while in fundamental they regenerate TP and MP(10% per skill activated), Like Ninja, perform certain combinations of the 4 weapon skills can create a additional healing effect depending on which step you end with. Jig = Cast Regen on allies within a certain radius of the dancer. Two Step creates a Barrier equal to 20% of the targets maximum HP, The Spin gives a small 5% increase to healing received for the next 12 seconds to all allies within a certain radius, The Slide = Reduces the Dancers fatigue gauge by 20 points. You can never uses a dance step more than once in a 3 button combination, so once you used that step it becomes temporarily unavailable.

Spells: The Dancer version of the time honored, Cure, Cure 2, AOE Heal, and AOE Heal 2, Raise, whatever their names they are spells just like the traditional healers, they cost MP no matter the style your in.

Skills: There are various skills called "Terms" that correspond to the various terms used in real world dancing, these "Terms" affect the dancer in various ways. Down Tempo = Resets the Dancers Fatigue gauge to 25%, allowing Dancers to remain in Freestyle a bit longer. Rhythm Allows you to gain the benefits of Freestyle while in Fundamental, and thus its only usable while in Fundamental, long recharge time on this one.

This was just a barebones off the top of my head type of thing. Honestly I could see Dancer being a DPS akin to Monk but borrowing heavily from FF6 Mog's style of dance where it changes the environment and utilizes various area based spells, and different idea though it is.
