U not really changing anything to be honest right now if we equip a staff we a white mage and when we equip a dagger we a ninja with all new different skills and traits so do the same. You have a great sword you are a drk and when you equip a sythe you still a dark but with all new different skills and traits. How many jobs can we bring to the game this could fix a few problems. For example if you really love dark but hate tanking than be a sps tank with a sythe
