Uh oh, that's like saying I came within 2% of a parse with a BB MNK as a scythe DRK/NIN.
Not really, 2x A- weapons, one is a multi hit A- weapon that's proc rate scales well with DA. In addition the possibility that you can add a 1h relic in main hand.
Toss in a jug pet and the ability to use most gear that war's can, and you have a very nice job.
If your a drk your not using an A- weapon unless your using 2h so you don't get the dual weild bonus, 2h weapons also have lower dps due to the current battle system, and guillotine isn't really supperior to rampage.
