WhoChallengedMe
Shows the challengers class in the duel popup notification window.
Specifically made for Swifty of Darkspear (www.twitch.tv/swifty)
*NOTICE*
This addon uses the /who functionality to gather the player data. There is an internal cooldown (server side) on this functionality (possibly 5 seconds) and as such won't be able to retrieve the player data needed. So expect constant duel notifications won't ALWAYS display challengers information.
Now supports cross realm characters and specialization about the challenger with the USE OF THE MACRO called WhoChallengedMe which is automatically created (on first duel request) and updated in your generals tab.
