What Tank & Healer Class would you like to see added in Expansion 3.0?

[TouchandFeel]

Tank

1) Rune Knight/Mystic Knight: An arcane magic tank that manipulates aether and seals it into Sigils that are used to either protect themselves and others or to infuse elemental power into their swords and attacks. Uses fencing/dueling sword and parrying dagger combo. Comes from the Fencer class with the possibility of Red Mage as a dps job that comes from fencer.
2) Samurai: A master swordsman that wields a two handed katana and utilizes exotic Sword Art and their formidable inner strength (Ki) to defeat their enemies. Would come from a new class, Soldier maybe?

Healer

1) Chemist: A scientific genius and master of aetherial concoctions and infusions that is just as home in a laboratory as using their brews and inventions to heal their allies on the field of battle. Based off of Musketeer (the pistol/gun class). Think Eorzean combat medic.
2) Dancer: A paragon of grace and skill, the dancer is able to manipulate aether and call upon the spirits of nature to heal and embolden their allies through rhythmic movement and dance. Would come from Rogue.
