In comparison to every other T10 DK piece in game as off the realse of 3.3 this has the best overall stats possible ATM
Going to be the most boss DK item. ever. caus i dont think they will focus in any way on DKs in cataclysm. in fact, all they've done so far goes towards goblins and geography and geomancers(hmmm. see a theme?) anyway, if you have this chest and or set, you are going to keep it for a long time. not only does the 2set combo work on enhancing the dmg of your best strikes, but the 4 set increases all dmg for everything. So my prediction sees us DKs through with this gear for the next 2 years, or until blizzard pulls a hat out of a rabit.
Though what chicera said is true that this does indeer have the best stats out of the T10 DK peices, what heyzeus7 said is untrue, after cataclysm came out, most people were replacing their epics immediatly, with only some of it staying until 82 or 83, you will not be using it for a long time, I am sorry that cataclysms technologies have went 100 years ahead instead of the predicted 10.
