So, now Monk/Dragoon have to compete with yet another class?

I doubt that Ninja can wear the Fuma set from CT.
Monk have it own CT set, Dragoon have it own CT set, Bard have it own CT set and Ninja would also get his own CT set.

Monk and Dragoon have differing sets because they have different defense priorities in their sets. Matching up ilvl to ilvl, Mnk has an equal amount of physical and magic defense, while Drg has more physical defense, but less magic defense than a mnk. Seems pointless, but it's a reoccurring element when the devs. implement gear for mnk and drg. Idk if they will connect Nin to Mnk, but their is a design reason behind giving mnk and drg differing sets (defense priorities) that might not be there when assigning gear to NIN.
