For all the things I dislike and loathe about the new changes, I was less dissatisfied than I thought I'd be. I think the one reason for that is the element of "counter attack tank". The dark arts proc off TBN for free edge of/flood of feels more, to me, to exemplify that counter attack tank feeling the class had in 3.0. I didn't feel that from SB DRK although it gave the resources to use a BS. I will miss the versatility and flexibility of 4.0 DRK.
