A UI I whipped up using the addons below! This UI is tuned for a square 1280x1024 monitor, but it can be easily made viable for widescreen monitors by moving around UI elements.
There is built in Feral Druid WeakAuras that you can use, I find them very useful, and they have been tuned for PvE
Just copy the Interface and WTF folders into your World of Warcraft folder.
Then go into the WTF folder and Change ACCOUNTNAME, SERVERNAME, and CHARNAME to your, you guessed it, Account Name, Server Name, and Character Name.
Once in game type /reflux switch GoreUI V2
Everything will change except SexyMap, which can be fixed by going to the SexyMap config and checking "Use Global Profile"
TidyPlates can be configured to your liking
Deadly Boss Mods
Hope you enjoy, and if you have any problems, contact me here, or email me at email@example.com. I will try to keep this updated to within an hour of a new patch.
