My paladin uses:

#show Holy Shield
/stopmacro [mod]
/click MultiBarBottomRight10

On MultiBarBottomRight10, I have:

#show Holy Shield
/castsequence reset=8 Holy Shield,Hammer of the Righteous,Judgement of Wisdom,Shield of Righteousness,Consecration,Hammer of the Righteous,Holy Shield,Shield of Righteousness,Judgement of Light,Hammer of the Righteous,Consecration,Shield of Righteousness

The second macro is 255 characters long, so this runs fine even without any addons. Honestly, I'd like double Judgement of Wisdom, but Light is a character less then Wisdom and I'm at the 255 character limit.

My shammies have:

#show Lightning Bolt
/Click MultiBarBottomRightButton9
/Click MultiBarBottomRightButton10

On 9, I have:

#show Lightning Bolt
/castsequence reset=8 Lightning Bolt,,,,,,,,,,,(comma's to 255 limit)

On 10, I have:

#show Lightning Bolt
/castsequence reset=8 Flame Shock, Lava Burst, Lightning Bolt, Lightning Bolt, Lightning Bolt, Lava Burst, Lightning Bolt, Lightning Bolt

With their level of haste, this gets me 1x Lightning Bolt and then Flame Shock refreshed just after it expires, with two Lava Bursts along its duration. Lightning Bolt spam in between. The reason for the first LB is to give my pally a moment to build a bit of aggro.

For the pally, I'm clicking a simple sequence, with each ability clicked at about the point it is clickable. For the shammies, they're going 1 LB, and then a castsequence.

I personally spam at 2 presses per second. For this team, I'm not really utilizing /Click to the fullest. Will definitely need to adjust my hunter in the mixed team - was using the /click's posted in the /Click thread.
