World mark spells, with that big green circle, can only use @player to drop it where you stand or @cursor to drop it where your mouse is. You also can't have a space between / and cast, and you can put those on the same line.
Code:
#showtooltip
/cast [mod:ctrl,@cursor] Tar Trap; [@cursor] Freeze Trap
For counter shot and pacifying shot, that's when you use @mouseover, which is for units. You also need a harm conditional here so that the macro doesn't try to cast on a friendly if you happen to mouse over one.
Code:
#showtooltip
/cast [mod:ctrl,@mouseover,harm] Pacifying Shot; [@mouseover,harm] Counter Shot
