best way to use focus for my 1pally 4 shamans

[Stealthy]

I use this to set focus:

/focus [target=Bugged, exists, help, nodead];[target=Shamin, exists, help, nodead];[target=Sheamen, exists, help, nodead];[target=Shaemen, exists, help, nodead]
/follow focus


Bugged being my pally then my shammy's. Then on all my toons dmg spells I have them target focus the /assist focus.

I also have another macro so all but the pally focus's on a shammy and they all assist of that one.

Yep this will work fine. I would add [target=Bugged, exists, help] at the end, as this will allow you to use it after a wipe when you're all dead and running back from the GY (that is assuming you had to change focus during the fight and need to see it back to Bugged now that you're dead).

Cheers,
