Rammoth, I think the point you're missing is that many addon authors who could help you out with either code or suggestions have not played Guild Wars 2 and have no idea how the UI functions. Reading a Wiki page about color coding in the UI with a few cropped screenshots of various portions of the UI isn't really helpful when you're talking about the feel of the UI in use. Instead of just saying "I want it to be exactly the same" you should try to describe -- in words -- some of the specific differences you want to minimize, and how the addons you've already tried fall short. If you can give me a specific description of the feature or functionality you want, I can immediately tell you if it's possible or not in WoW, and whether there are any addons that will give it to you, or where you should start with writing it yourself.

Otherwise, you're really limiting yourself by requiring anyone to have played GW2 before they can help you, especially when you're posting on a WoW-specific forum.
