Vanard sent me his UI with a detailed email telling me exactly what he's using, and you should do the same! We're getting a lot of healer UIs, we had Synchrony's priest UI last week, and my own UI the week before. We need some tank and DPS UIs! If you do email me on firstname.lastname@example.org, tell me what addons you're using, why you're using them, what you like and what you'd change. And don't think you have to use a ton of addons, I'd love to feature a customized version of the standard UI.
I challenge you!
Actually, let's call that a challenge! Send me your best UI customization that only uses standard Blizzard UI elements. You can use addons to move them around, reposition, re-size, but it has to be exclusively Blizzard frames visible. Points awarded for using fewer addons, and for innovation, or doing things that most of us don't realize the Blizzard UI can do! Do still send me your normal UIs, as well.
