Arena Raid Icons automaticly sets raid icons on your team at the start of an arena game (if you're the leader). The addon was orignally written by someone else (forgot the name) and I have been using it for a while. After requests from some people I decided to make it available to everyone this way.
----------------------
1.1 Fixed a bug where sometimes the raid marking would not be applied.
1.2 Fixed a bug where the addon would cause bugs outside the arena sometimes.
1.3 Updated for 7.1 and addon is now no longer trying to put certain marks on certain classes.
