They are not as OP as they once were. They still have a secure spot in raid scenarios at the moment but they are certainly not OP. Many people might say they are a little bit underwhelming compared to other jobs but they certainly have a spot in raid groups.

As far as what to roll it would really just have to depend on whatever you're most comfortable with. Pick the job you find the most fun and go from there. Heavensward isn't too far away so all of this really could change a ton when that drops. Play whatever you'll have the most fun with for now.
