However if SE does decide to make DRK to wield both weapons then perhaps DRK it would be best if it is it's own class that has nothing to do with PLD. Make it where it can be a tank class or DPS class. The great sword side of it can be the tank side of DRK, maybe taking some moves from MRD since it has a similar slow/heavy weapon movement and use it to carry over some abilities. And the scythe side of DRK can be DPS where it takes moves from DRG where it can carry over some moves from it as well.
