In an attempt to open some discussion on this, given recent news of our possible venture into asian-esque territory some time next year, I wanted to jump in and see what others think tier gear will look like for classes in this new land? Here are a few possibilities I've come up with.
Rogue - Classic Ninja (hopefully they'll not tear away the undead's clothes this time, but they probably will)...
--------- also suggested was Scorpion/Sub Zero. (credit Ultramonkey)
Warrior - Samurai
Death Knight - Shogun/ronin (similar to samurai, but more dark and weatherbeaten)
Hunter - chinese dragon also suggested chinese lions (Credit Hawt09)
Mage - Japanese Kimono
Paladin - Feudal lord (similar to samurai but with the flaired bottom as usual and more pronounced lordliness to it)
Priest - Budhist robes
Warlock - Oni
Shaman - Raijin Theme (thank you mortis darkskull)
Druid - Kitsune appearance. also suggested Bansai trees for Healing set.
I need to flex my photoshop skills at some point, but if anybody wants to take a stab at one or more of these would be fun, I think.
*EDIT* Added links to possible ideas.
