This is the UI i created for my priest.
It is working good for any healerclass, just a few class specific changes should be made in Grid and Needtoknow.
It is designed for 1920x1080(widescreen) and i am not planning to create it for other resolutions, so if you play on a different resolution you probably have to move things around a bit.
All credit goes to the original addon authors, i only take credit for the design of the UI and the artwork.
1 make a backup of your own interface and WTF folder(for the ppl who dont know.. you can find them in your World of Warcraft folder).
2 Download and extract my UI on your desktop or anywhere you want to.
3 Go into the WTF folder, enter the account folder, and rename the folder called YOURACCOUNTNAME to your own account name, all in caps.
4 Enter the accountname folder and Change the folder called Yourserver into your servername.
5 Enter the servername folder and Change the folder Yourcharacter into your Characters name.
6 Put my WTF, Fonts and Interface folder on the place where your own folders used to be(in the World of Warcraft folder that is).
Most likely when you login game now it will look like a mess.
