Easy fun dps class to play

[FunkYeahDragons]

I'd probably choose based on what you don't want, since easy is a matter of opinion. Dragoon, Ninja, and Monk have positional attacks (attack from back/side/etc) and combos. Bard has damage-over-time skills to watch and later has cast times, Black Mage has poor mobility and is Black Mage, and Summoner has damage-over-time skills and pets to micromanage. The last three are squishier, too.

Don't avoid Dragoon if you like it. I leveled it to 60 and it wasn't that bad around 30, and you can cross-class some HP recovery skills for solo questing.
