"Since ICC, [Insert X job here] have been slowly losing everything that made us unique."
My experience with DK is very different than Warrior. But I tend not to look at the individual abilities and more look at mechanics. That said there is a move to hybridization because of PvP even among the DPS classes (CC breaks, self-healing, etc.) but I am not going to touch the PvP vs. PvE design debate here.
What I don't understand is that you say you are losing unique things, and one of them is something you are getting back. Corpse Explosion. I actually found the DK talents to be some of the most unique and interesting talents. And perhaps most importantly, it looks like they have a tier of talents that actually effects game play mechanics for the class so you can pick the rune regeneration model that you prefer (yes, one will likely parse to be better, but I have found that this kind of thing can massively effect DPS if you can't control the mechanics correctly).
That said, let me reemphasize this: ALPHA IS ALPHA.

The problem is that you are looking at some new things and some old things are the same time. Honestly, for now, I would just look at things in a vacuum and not as a whole yet.
If you want to see some lame talents, go look at what the Rogues have to put up with... yuck. Your grass is far more green.
