I decided to sort this out myself recently as the camera angles on the other 4 were always shifting around, making placed AOE less efficient.

What I did was add two new macros to the Macro set, the first to set the other clients to view 4 (executed twice to make it an instant view change)...


the default view 4 is zoomed in too far for my liking, so I have a second macro to zoom the current client back to maximum zoom out...



Then I just added calls to these new macros on the end of the Follow key map, sending the view macro to all others..


and the zoom out macro to current...



I did have to exit and restart WoW for these changes to work - I guess it's because they use ingame macros.

Hope that helps.
