So... the part about Gunbreaker doing more than SAM/BLM is utter nonsense. Gunbreaker right now falls in between the DPS of Warrior and Dark Knight that are usually able to be doing nearly as much damage as the lower end support DPS classes. Gunbreaker is far from broken, instead alot of DPS jobs current numbers feel "off" to say the least.

Dancer is going to be on the lower end of Damage because they are the most DPS support class in the game so their damage helps others rather than just themselves.
