So... in theory, you could bind the 'g' key to do different things on each of the toons

To create a cross formation, backpedal your main into the bunch and have one of the toons with 'g' as backpedal, one as strafe right, one as strafe left and the last one to move forward.

And if you have the DBM addon installed, create a macro that lets you open /range so that you can spread out to 10 yds apart.

Now I am going to have to try this one when I get home tonight
