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

Ninja will be competing with Monk. If it isn't then someone at SE is a massive troll for adding Fuma to the game so early.

Also, as for what stat Ninja will use... Why can't it use both? White Mage uses MND and INT, and has an ability which swaps them; why can't Ninja have an ability that converts its STR into INT for Ninjitsu? Or DEX, whichever floats your boat.
