For future reference, I just want to list the basic Seduce macro I'm using for CC. This is not really for boxing, but putting a separate focus hot key on each Warlock using a Succubus as well will make it a very powerful tool.

/clearfocus [modifier:alt]
/focus [target=focus,noexists]; [target=focus,dead]
/clearfocus [target=focus,help]
/petstay
/petfollow
/stopcasting
/cast [pet:succubus,target=focus,exists,harm] Seduction; Seduction
