Dancer Tank!!!

[Duelle]

Looking for input while trying to get this idea together. Barebones version for now:

Dancer

Weapon: Shawl. Note: DNC's style of fighting involves "iron cloth" techniques, where the shawl is moved, pulled and spun in such a way that it is capable of cutting flesh. And yes, these weapons would be made by weavers.

Core Mechanics: DNC is designed around generating finishing moves and consuming them to deal damage or mitigate incoming damage. Their primary method of mitigation is staggering damage (70:30 split). Good candidates for secondary mitigation would be parries (no samples presented) or self healing (Drain Samba).

Abilities
Animated Flourish - Increases enmity generated by your abilities for 30s. Cooldown: 20s. Only one Flourish effect can be active at all times.
Violent Flourish - Increases damage dealt by 25% for 30s. Cooldown: 20s. Only one Flourish effect can be active at all times.
Drain Samba - Converts 10% of the damage dealt by auto attacks to HP for 20s. Only one Samba effect can be active at all times.
Haste Samba - Increases skill speed by 10% for 20s. Only one Samba effect can be active at all times.
Feather Step - Increases evasion rate by 30%.
Steel Wing - Delivers an attack with a potency of 180. Can only be used after Evading, Grazing or Parrying an attack.
Perpetual Motion - Increases evasion rate by 75%, but converts all Evades into Grazes. Effect ends upon reuse.
--Graze - You barely evade attacks, causing 70% of the damage to happen instantly and the remaining 30% to be divided over 15 seconds.
Healing Waltz - Converts damage over time effect from Perpetual Motion into a HoT that heals for 20% of the projected total damage over 12 seconds.
Deflective Sweeps - Reduces damage taken from the next three attack by 40%. Cooldown: 60s.
Aplomb - Perfectly evade most attacks for 10s. Cooldown: 420s.

Notes:
- Unlike WAR's Wrath system, finishing moves (I'll think of a better name later) can be consumed piecemeal. I was thinking of setting the max at 5, with Flourishes requiring 3 finishing moves, Sambas would require 2 and Steps/Waltzes requiring 1.
- As probably noted, Flourishes are effects that mimic stances. Animated Flourish would be the default tank effect while Violent Flourish would allow the DNC to go into DPS mode as needed.
- Flourishes can be activated for free, but require 3 finishing moves for the effect to be refreshed.
- Adding to the above, Sambas also play similar roles, with Drain Samba being meant for tank upkeep (not burst drains like WAR and DRK have, but an effect that can be kept up full time for minimal healing over time).
- Perpetual Motion and Graze are meant to allow DNC to mitigate hits from enemies without having to wear heavy armor.
- Healing Waltz plays into this as well, since it converts staggered damage into a HoT. What would happen is your staggered debuff (indicating the amount of staggered damage) would vanish and you'd receive a Regen effect. Your stagger "count" would go back to 0, allowing you to continue to stagger damage while the HoT is still ticking.
- Aplomb is DNC's answer to Hallowed Ground and would be subject to the same limitations.

PS: Here's your stance-dancing tank. :O
