Incredible. Thanks for sharing.

When I first tried it I kept getting the targetting overlay and was a little disappointed. Then it just started working and figured out why. There is one little gotcha. It appears that you must be standing on the actual terrain and not any raised flooring like the center of Shattrath City or the rock parts in Lower City. I'm not sure how this works inside instances that have 'floors' Either way I'm sure it will raise the fun factor of 5 boxing locks in AV that much more, and would make a nice 'pop that stealther' spread AOE.

Let the AOE shows begin! Infernals, rain of fire, laser beams, hellfire, portals...

To coordinate your clones who may not be facing the right way, you can probably do /script Minimap:PingLocation(Minimap:GetPingPosition()) in their macros so they will get the appropriate relative position of where you main casted. You would have to stagger the cast to take into account latency for the minimap ping to make it to the clones. This also means you need to have /script Minimap:PingLocation(X,Y) in your main's macro twice since the first one appears to be gobbled up and never actually pings the map.
