After doing some digging in Patch 3.2's latest PTR files, I've assembled a gallery of the new Horde Tier 9 plate sets. The shoulders are slightly unfinished, or at least looked like they were in WoW Model Viewer. The gallery includes Death Knight, Warrior, and Paladin themed sets. In a move that bodes well for Alliance mail armor, the Horde Paladin sets are blood elf themed, so we'll see how that goes for our Draenei Shaman friends (read: me).
I'm not too upset about the looks, myself. They look very Horde, even if the helm screams "Onslaught", and the colors are quite different for each class -- even more so than on the Alliance plate pieces.
Have a gander and enjoy! I'll dig through every new PTR patch that comes out looking for the Horde cloth and Alliance mail and leather sets, so keep your eyes open for updates here.
Patch 3.2 will bring about a new 5, 10, and 25 man instance to WoW, and usher in a new 40-man battleground called the Isle of Conquest.
