My DPS roles

So I now have at 80 and geared out in 440-450+ a Black Mage, Red Mage, Machinist and Dancer.. what is making me chuckle is the comparisons on their DPS.. on a level 80 dummy my DPS is ranking as

1 - Black Mage (kinda expected this)
2 - Dancer ( What the #$% ??? )
3 - Machinist ( meh ok )
4 - Red Mage ( sad Panda )

I don't know if it's just skill or the classes I like better or what but has anyone else run into this??

Dancer, Machinist, and Red Mage are the worst 3 DPS currently now that ninja got buffed.
