adding positionals to nin seems a much lighter game play change than what they are planning for mnk and drg. heavy thrust timer and adding another step in the combo will probably screw over drg's rotation pretty hard. or dropping greased lightning on purpose to actually achieve a higher dps than by just "dancing" around the mob.
Just wait on the actual changes. in the end nin might be the easiest close ranged dps while putting out similar damage.
Though i do understand that all other classes seem to get much flashier additions compared to nin. but maybe cause nin is just a well designed job to begin with, that already had heavensward in mind when it got introduced.
