Not sure why everyone is thinking Dancer will get ninja gear. All the Magical DPS share the same gear, same as tank and healer, so why not Ranged Melee? It would be weird that 1 ranged DPS would not share with the other 2 when all of them are a mix of DPS and support.

As for the style, I can see the ranged DPS in 5.0 following this set up: Machinist being more DPS with just a little support(like others have said the black mage of Physical), Bard being an even mix, and Dancer being more support heavy then personal DPS. They easily could be very buff happy but by themselves they aren't DPS masters. instead they bring a ton of Buffs for allies for attack, defense, and other ways. Maybe a Dance that has health Regen(like how Red mage can be a back up healer), a haste dance, and also Dances to effect enemies like a slow dance, and a sleep skill like dance(would instead be mesmerize that makes a group of enemies just watch her dance and do nothing during it)
