I really, really like the look of the Tundra Pauldrons:
This is right about dead center for my tastes in medieval-ish fantasy armoring. It's not realistic. (Of course, neither is night elf physiology, and I make no secret of the fact that I do like playing implausibly thin characters. My escapism, let me share my thoughts.) But it conveys—to me, at least—a dramatic appropriateness. Yes, this is the sort of thing that the peoples of cold, undead-haunted lands should make to defend themselves, and it takes a hero with strength and experience to make good use of what she's taken from her fallen enemies' persons and treasure chambers.
Innovative? Nope. Classic and entertaining? Yup.
