I agree that DRK does not look like it is changing much. In an expansion you usually have some fresh animations and a slightly different feel for the new expansion, like how Spirits Within got upgraded to Expiacion. Although we do have extra off-globals to press which DRK already has a lot of. The biggest change actually seems how often we will be using bloodspiller because of the reduced recast time of Delirium.

I don't agree with the "DRK is WAR" thing. They are substantially different tanks. DRK is about absorbing damage with TBN while WAR is about taking that damage then healing it back up. DRK is about off-globals while the WAR rotation is primarily on the GCD.
