Fastest DPS to quest with

[KDSilver]

Samurai is the highest individual DPS right now in the game followed by Monk and Black Mage.
I won't recommand Monk because you have to do positionnals to output the best dps possible. Won't recommand Black Mage either cause he's a turret, need to move and lack of self heal, even though he has a barrier.
Samurai sounds like a good option.

Otherwise, Red Mage is a good option. Not the very best dps but easiest rotation to learn, very good damages, mitigation and self heal.
Probably one of the best dps to do solo content.
