This is the orcs panel from Warcraft III, I made major modification to it to fit into the UI of World of Warcraft.
This one was designed specifically for the Horde faction, I might create one for the Alliance in the future.
There are three versions of the background to this panel, choose whatever you like.
How can I use it?
To use it you will need to download one of these addons or build a custom panel yourself.
