SE could move NIN from slashing to piercing. Would be
Slashing 2/4
Piercing 2/4
Blunt 1/1 (Monks feel so loneley; when will a Job with a Hammer appear? Q_Q)
then.

Giving it either MCH or BRD, would make 1 Job superirior to the other (just a bit. But you can bet the other Job would whine about not getting it)
I guess we have to deal with it until new Jobs arrive into the game.
