Literally unplayable.
When you create a Death Knight, or select one in the character select screen, the buttons turn from red to blue, making your entire screen just scream death and cold and darkness.
When you create a Demon Hunter? Nothing. Just another character. No big deal. I only start fucking 40 something levels higher than the Death Knight, but, nah, I can just use the same old tired red buttons we've seen since 2004. Not green or anything.
I'm hurt.
