I actually want to see a DRK come from GLA and wield one handed swords with no shields. Like dissidia Cecil's design. Granted, he wields it like a two hander iirc, but it was pretty much a short pointy stick. Can just turn halone combo's enmity into extra damage (at the cost of hp?).

The rest would be drk skills costing mp (hp drain attacks to compensate for halone's hp cost?) with riot blade to keep mp up plus a new finisher for the riot blade line.To make it even more suicidal like the typical DRK, make the 3rd attack after riot really desirable but add a position requirement...from the front. DRK's death rate should give arr's dragoons a run for their money.
