Got this last night for my rogue. Replaced the Bloodknight War Cloak.
With both cloaks having the +12 agility enchant, you gain a total of 1 agility and a nice chunk of hit rating over the BKWC with the DofDR, but lose about 13 AP and 10 health. Gains of crit are next to nothing, something like .04% if I remember from rating buster, but a gain nonetheless. This item is prioritized over the BKWC because of the hit rating and nothing more for us rogues in my opinion.
