I use 3 buttons very much when boxing. These buttons are on all of the "secondary" characters hotbars.

- /follow MainCharacter (I put this on the 0 numberpad button because its big) I hit this button a few times after I kill a mob to make sure everyone is following.

- Char2 strafes left, char3 strafes right, char4 backs up, char5 walks forward. This is bound to the + key on the keypad. Right before I get to a mob, I hit this button so that all my characters spread out a little and stop following the main.

- /assist MainCharacter (I put this on the '.' key next to the follow on the keypad) After the characters spread, I hit this a few times so that the mains have the correct target.


With this setup, you never have to "macro" any of your offensive spells because they will already be targetting the main's target.
