Hmm I am using focus since my first day of boxing, and yesterday I tried the Rocket Car Parts quest in Thousand Needles (I skipped with my first team) and was a pain in the ass, as I was trying to control a slave being as main and just didn't work, as the macros are all focused based on the main's actions, targets, etc.

Yes, I changed focus of them all, but anyway macros didn't work, because is based on focus. Anyway, a big mess.

I will try this. I am just worried about pet.

For the Warlock pet, I once used (warlock Smash DPS Key):
Code:
/petattack
/castsequence [target=focustarget] blahhh..
Then the pet just took a random target, as he is not taking focustarget, only the castsequence. I changed then to:
Code:
/assist focus
 /petattack
 /castsequence blahhh..
And it is working nice.
So I now may try how the pet can attack the same target if the "Smashing DPS" goes to your idea, WITHOUT changing targets:
Code:
/petattack
 /castsequence [target=targettarget] blahhh..
I will test if /petattack [target=targettarget] works. Otherwise, I have no idea.
