Works like a champ, just have to remember not to spam it.

As you mentioned, it might be the focustarget parameter. Try just doing /target focus and then /targetlasttarget instead.
If you have a focus do macros automatically assist that focus?

Thanks for the sequence by the way, you just saved me three buttons on my x-keys.
