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.

[Rampage]

Magitek Tank! Wearable magitek gadgets , use mainly damage soaking barriers, traps and bleeds. Put energy barriers in front of you to mitigate damage. Set up agroo traps behind enemies, if you lose hate and an enemy steps over the trap it blows up giving mob a debuff and regaining agro. Use multiple DoTs on enemies to keep hate. Have explosion abilities with very small knock-back to position enemies in front of your barriers. Main weapon could be ranged even. Make it more about managing the positioning of your tools and barriers and keeping up DoT rather than running around bashing stuff.
