Dear SE. I'd really like to see you continue the tradition you created with Dancer, that was mimicked in Warhammer Online with Warpriest.
And that is the Front Line Healer. A Cloth/Leather Wearing Melee Fighter who uses their melee attacks to fuel abilities that assist the party with healing and minor buffs like Haste, Regen, Protect, etc.
When Dancer came out on FFXI it literally became my favorite job and sub job. It changes how a player could play jobs like Warrior and Samurai. I could actually MAIN HEAL as a Samurai with Dancer Subbed. This was quite possibly one of the most fun side effects of the Dancer Jobs implementation.
Now I know, not everyone even likes the idea of a Front Line Healer. For some reason they hate the idea that a healer is on the front line, can deal damage. And Damage Dealt is used to Heal others. But I LOVE this idea. Its still very unique among MMO's, and i think FFXIV would benefit from a class and job that can perform this roll.
