Yup. <3 Except the Heavensward Jobs start at level 30. I would recommend giving all the classes a try and then sticking with one to get through story.

Bards can do a lot of damage on their own (I've seen a lot out-DPS most casters), but it's mostly their support songs people are keen on lol. And just to warn you, the "moving and casting" won't last. I know a lot of people quit Bard once they get to higher levels because they hate having to stand still for the higher level skills.

I would recommend looking up a rotation/opener guide, if you're unsure. There might be one in the DPS forums (it's where I found mine for Summoner), but google will probably have something.
