Just signed up to say: THAT'S THE BEST IDEA I'VE EVER SEEN FOR LEARNING MECHANICS SINCE WOW'S FIRST LAUNCH! (I'm a player since Vanilla)
There are a lot of good ideas in the comments, but I'd wager it's not an easy, at first glance, payless job.
But I'm happy that there's a possibility of supporting it! And I must say, this is what wow raiders should be investing their extra money on! Much more useful than buying a mount in wow store AND many other stuff wow-related in my opinion. ;)
I hope other people help out as I'm about to. Keep up the good work!
