I will be going for a very dirty, hordish look for my undead DK come WoD. I'm getting bored by all these clean looking sets and I want to try something new for once.
It's very edgy and you somehow get the feeling you might get tetanus the instant that blade scratches your skin. Still, I want to keep it blue to match it with Forsaken flags and the Forsaken Warhorse + Bloodbathed Frostbrood Vanquisher mountpair.
Because of the set having blue as main color with lots of secondary colors (white, brown and greenish + grey/black) all colors of the different ghouls still fit in the overall image, the green/purple look of the darkly transformed ghoulmonstrosity doesn't stick out and many spell effects which don't fit a blue-oriented set like bloodlust or death and decay don't feel out of place.
Also, the bolts and nails match engineer nicely.
I just have to wait for S15 now to start collecting. I might look like everyone else in the beginning but with time people will stop wearing that and I might even stick out a little.
