I'd be interested in the general philosophy of targetting/assisting. I am currently using all DPS targeting through /assist focus, and have a separate focus/follow macro that chooses an alive party member in a certain order. 4-shammy teams seem like they have some flexibility since you don't really need to reserve focus targetting for CC (sheep/seduce) activities.

Specific macros would be great, but I'd really love to hear about the general macro philosophy as well.
