And as an optional choice that is fine, but they primarily advertise it as controler compatible the last time I checked. Forcing keyboard and mouse controls on people that use a television to display the game in their living rooms is far from a sound idea, hence you'd end up either with clunky controlls or you'd have to cater to the lowest common denominator. Personally I can't even imagine how awful Samurai or Black Mage must play with a controller, let alone healer. Yes I know you can do it, but it really takes some geting used to it and I wouldn't exactly call it great.
