Well, it won't be in the top 5 of best looking DK sets, but it's the best we've gotten this xpac IMO.
My biggest gripe is the open neck area. Why would you wear all that armor and leave your neck so vulnerable. That just looks dumb.
And I don't understand why they can't make shoulder armor that looks like it might be attached to the rest of your armor. Most look like they could fall off with a light gust of wind. Shoulder armor needs to look more "sturdy" in general.
My only other thought is that the actual design needs slightly more contrast. Some of the colors are too close in value. That makes it look very similar to the generic gear found all over in MoP.
I do like the theme of the set. It's a nice change of pace. No skulls! lol
