I have F1-F5 (for slots 1-5) assist the hot character and then set focus, and then I use keybind "\" (its a nice big key above the enter key on my keyboard, I chose it for the size) to cc all. my isboxer CC macro is:

/stopcasting
/6 CC1
!if (character in "Shaman") /cast [@focus][] hex
!if (character in "Mages") /cast [@focus][] polymorph
!if (character in "Paladin") /cast [@focus][] turn evil
!if (character in "Warlock Destro") /cast [@focus][] Enslave Demon

and my CC2 key is Alt + \


/stopcasting
/6 CC2
!if (character in "Shaman") /cast [@focus][] bind elemental
!if (character in "Mages") /cast [@focus][] polymorph
!if (character in "Paladin") /cast [@focus][] turn evil
!if (character in "Warlock Destro") /cast [@focus][] Banish
