The Wrath of the Lich King icon can be found here: [link]
Here's a World of Warcraft Icon. I took a look at some cocept of the game and like this image the best, so i decided to use it for the icon.
I made it as detailed as possible, adding the green rays and some shadow.
I'm considering making one for the original game, without expansion, but i will have to decide which image to use since the original game has so many factions.
It's Vista ready and includes the following sizes: 16x16, 24x24, 32x32, 48x48 & 256x256(PNG Compressed) in RGBA (32 bits) & 256 (8 bits).
256x256 PNG file included for dock icons.
