Honestly, the classes and jobs we have so far are pretty well balanced, enough that there's no bad choice or obvious choice. Hopefully, SE will be able to maintain that as the new ones are added, though of course the more jobs we get the harder it will be to keep them both unique in flavor and yet equally useful.

Archer/Bard does some solid DPS, with advantages in both range and mobility that make avoiding enemy AoE, as well as a lot of dungeon mechanics, easier. As Bard, you'll also pick up some songs for group support abilities. In a straight out DPS race it may not be quite at the top, but you can usually make up for that in better up-time than casters whose spells can be interrupted or melee when they need to dodge out of the way of something and are momentarily stuck beyond the attack range of their primary skills.
