As someone who has formerly played a rogue, I must admit I've become somewhat hooked on seeing what sort of UI you're using. You do a lot better at the bare-bones, high-utility UI than I do, and if you wouldn't mind, I'd like to see a picture of what you have for your DK. I'm working from the same basic UI I had on my rogue, plus a mod for runes and a new cooldown tracker (CooldownTimers3 is not DK-friendly). There's always room for improvement, though, so it's good to see what others have got.
Sorry if you've posted any pics recently, I looked around and didn't see anything. Thanks!
