DNC should be still fairly popular as a new job. But really, it just depends on your playstyle and what you want to do. If you go by personal DMG it's MCH > BRD > DNC, if you go by raidDPS it's DNC > BRD > MCH.

Of course, it also depends on the fight / content.

For example, TpS - the guys with the world first clear in Alexander Ultimate - stated that this is a fight designed for BRD and it's best to bring one over DNC or MCH.
