Well the PTS came up, I managed to take a couple of screenshots then my client crashed and I can't get logged back in as the test realm is full. So you will get the graphics today and time (and the PTS) permitting tomorrow I'll grab screenshots of the full stats for both sets for reference again.
One key thing, the sets DON'T come with belts or back pieces. The rr98 belt is actually the same style as the Warpforged so we can assume it goes together (graphically), but I didn't see a belt that went with the Doomflayer set in my backpack so the Black Orc looks a bit slimmer than normal.
I like the Warpforged set and even the Doomflayer set looks nice however the helm I don't know if I love or hate. I love how it's a big, clunky bit of metal with spikes and bits welded on, but I can't seem to shake the image of a droid from Star Wars when I see it. I think playing around with some dyes could net some interesting results, but in the meantime here we go.
Doomflayer (no belt, no cloak)
Warpforged (with rr98 belt, no cloak)
