Hunter's Mark + Pet Attack w/Misdirection...?
 

I just found this macro... to cast Hunter's Mark on the target and command the pet to attack if I'm not in a group or already in combat; otherwise it will just mark the target if I'm in a group and not in combat.

#showtooltip
/petattack [nogroup][group,combat]
/cast Hunter's Mark

I have another one to misdirect my pet: /cast [target=pet,help] Misdirection

Would it be possible to combine the two? I'm not really good with macros. My first hunch is to add the pet misdirect macro to the first one, but I feel there should be something in-between - like /stopsequence or something?

EDIT: this may be a stretch... but is it possible to have a similar macro to the first one, and add misdirect to the Focus?

like that? Thats what I've used on my hunter for a very long time. MD's to pet if you dont have a focus or focus is dead, and to focus if focus is alive and kicking.
I'm not real sure how you would add MD and Hunters mark in one macro. I believe they both are on the gcd

1) Misdirection and Hunter's Mark are both on the GCD, so you can't cast them both with a single keypress.

A little code simplification on the MD macro, and add "follow normal casting rules if there's no friendly focus and your pet doesn't exist" to who to MD.
Basically will MD to your friendly Focus target if one exists, then to your pet if it exists, and then to your target if neither of those exists.
