Amnix UI
Having gone weary of the default wow UI, I decided I'd give it a try and make a fully customized and minimalistic UI intended for both PvP and PvE.

This UI is intended for 1920 x 1080 resolution



Install:
Before installing this addon, make sure that you take backup of your WTF and Interface folder. After that, delete your wtf folder from the \World of Warcraft folder and then extract the Amnix UI.rar file's content to your \World of Warcraft folder. Next, doubleklick the WTF folder and rename the subfolders ACCOUNTNAME, Servername and Charactername to your account-, server- and character's specific names.

Features:
A minimalistic addon with the intention of being useful for both PvP and PvE and focuses on displaying vital information and not cluttering up the screen with useless garbage.
Raid Frames are the Blizzard default one, so you might have to disable the raid frames during a party group of 5 or less.

If you got any question, please post a comment or send me a text and I'll try to answer as fast as possible.

NOTE: You might have to load in the addon profiles in-game. To do so, go to the selected addon's profile page and choose "Copy From" and then select Ixm, the ones I can think of (aka most crucial) are the following:

/bartender
/quartz
/masque
/pitbull
/omniCC
/rbuff lock/unlock (for moving the player auras around, they should by default spawn at the top right corner next to the minimap)
/omnicc (select the "Text Position" tab from the OmniCC menu and select the "Top" or "Bottom" anchor. THIS ONLY HAS TO BE DONE IF YOU WANT THE ENEMY BUFFS ETC. TO LOOK LIKE MINE)

If you're encountering any problems with these addons, please let me know.

Addons included:
AmnixError -- Removes the annoying red error text "can't do that while casting, etc." on your screen
Bartender4 -- Actionbar mod
ButtonFacade -- Button styler for actionbars
Ferous Media -- Media package for custom healtbar textures
Gladius -- Arenaframes
InterruptBar -- Displays enemy interrupt CDs
LnS_Minimap -- Squared minimap
Masque -- Same as ButtonFacade
Masque_Renaitre -- custom skin for Masque/ButtonFacade
OmniCC -- Displays cooldown text
Pitbull4 -- Unit mod
Quartz -- Custom cast bars
rBuffFrameStyler -- Custom buff and debuffs
