Macros are the way to go. I click my opener for my pally, then mash the '2' key for the rest of the fight for all five of them to do their thing.

Clicked:
Dynamite
Avenger's shield
Exorcism (if needed)

pally:
seal, judge, consecrate

shaman:
chain lightning, LB, LB, LB, LB

The pally gets and keeps their attention. Shaman open up a can of massive DPS since the pally output about 2.5k threat in the first two seconds at lvl 58. Dynamite is used to pull since I've had a few less than fun jumps by the shield. (group, pat, different group for a 7+ pull) Single pulls I just smash the '2' key and don't even worry about clicking things.
