For those who don't want a moddable ui and say it'll add clutter and here look at the worst wow UI I've found ever that uses the default hotbars and map and 3 mods that haven't been resized or anything... look at this: http://www.wowuigallery.com/topic/tukui-v10

Addons don't necessarily mean clutter.

And maybe I just haven't looked at the screenshot hard enough but I see NO change in art style and it still looks pretty damn realistic. I want to know where this "it looks like a downgrade I don't like the style" is coming from.

I think that screenshot looks amazing and I'm excited.
