Dancer - Blue Mage, how they could be done interestingly

[Duskane]

Problem with BLU as a tank and DNC as a healer is they would need to do something that can't be done by other jobs in those roles which would be difficult given the game's design. What could BLU do that isn't done by the other three tanks when one is already the odd man out?

Aesthetically Blue and Dancer would bring more the the roles
Holy tank
unga bunga tank
angst tank
alternative magic tank

with tank gameplay of course the main idea should be there
but i think they could spice up tanks game play like Paladin and warrior basically play the same just one has more utility
while Drk is more about speed
forth tank could have a job gauge like Drg,Nin,BLM etc etc that could also be fun and unique for a tank

if dancer had spells with different combinations like mudras (just not as laggy) making it somewhat a fast pace healer would be okay
i dont think it would work out too well as a close range attacker though

id be content with Blue mage or Gunblade as a tank

Dancer would probably have a split between TP based damage skills and MP based heals. I'd like them to get a Synastry-style oGCD skill that they just mark a player with to guarantee they get a passive heal every time the dancer uses a weaponskill. Unlike Synastry, this would always be available, and using certain abilities could empower the healing done by the mark. It would be their regen/fairy equivalent. This ability would also be tied to other cooldowns, like an AoE heal (comparable to Cure III in range and indom in potency/cooldown) that originates from the marked target, a mitigation tool for the marked target (Basically Rampart), or a damaging AoE skill around them.

I'd like an enemy equivalent of the healing mark as well, that would trigger a weak damage nuke on them if you used spells. This would mostly be for proccing debuffs, since that is another aspect of Dancer's kit. This would include Disable, their raid dps cooldown (probably Vul Up), a bleed DoT, an AoE stun centered on the target on a cooldown, and a reliable Silence. Maybe introduce a stack-based nuke debuff that the party could trigger by attacking them, that way it always totals the same potency, and gives them some spike DPS in raid CD windows. Could even have the marks interact with a cooldown that allows the marked ally to trigger both marks when attacking the marked enemy with a spell/weaponskill, boosting the throughput of both. A personal cooldown could enable the dancer to trigger both marks regardless of whether they're using a spell/weaponskill at the time.

I'd expect Dancer to not have very much shield-based mitigation and instead rely on percentage buffs/debuffs and empowering these marks to carry their throughput through a fight. They'd still have the standard Cure I/II/Medica/Raise equivalents, a basic weaponskill combo, a filler DoT, and an AoE skill, but like Scholar they'd rely more on using their shorter cooldowns and matching them together to carry them through a fight.

I really like the sound of that Dancer set up.
It didn't occur to me to utilise damage debuffs in place of shields, but it makes perfect sense. I had wanted Dancer as a debuffing melee DPS before but now this seems much better.
