If you use this macro you have to use the ? as the icon for it....
Code:
#showtooltip
/cast [nobutton:2,target=focus] misdirection
/focus [button:2]
What this allows you to do, before you start the instance or the raid, you target the MT and right click this icon..
Then throughout the whole instance, if you left click this macro, it will place MD on the MT without having to focus on him, no mistakes on putting it on wrong party member and its super powerful and small.
