WOW Quest:Keeping the Alliance Blind (13331)  

Due to the speed with which the targets move, hitting them can be... annoying, even with a 100 yd range. I recommend the following macro:

#showtooltip
/targetexact [nodead] Skybreaker Recon Fighter
/cast SGM-3
/run UIErrorsFrame:Clear()

Spam that even when you can't see them; if you pick a good spot, there's an even chance one is around, just not in your field of view.
