I miss too the DRK from HW, the one without a burst (I mean a very high spike of dps), the DRK who is able to tank like a PLD or dps like a WAR, with complex rotation and all. But I miss AOE rotation of SB.
However, the new DRK from ShB is imo better in overall than the SB's one, so... I'm hesitating to complain.

If I should change one thing, it's the Delirium = IR. I think there is no point at the beginning of spamming on spell 5 time for a burst, I don't like it from the WAR, I will not like this c/c for the DRK.
They really should give DRK another combo, even if it's similar to the WAR or the PLD, something else to do 123 then BS...
