They are giving DRK updates that follow the jobs traits in past versions of Final Fantasy.

DRK has always been a Hybrid WAR with BLM traits, which is very conflicting and difficult to be original other then giving exclusive Scythe/Great Sword WS.

There is not much left for DRK in terms of upgrades, it has all the original abilities and traits, all they could do really for the job currently is give it a MAB + triat and more INT over STR in the up coming levels to give it the balance its lacking.
