If your German is up to snuff, rulemaker's post is much better than mine. Here is what I use

Button 2 Pally
Code:
#showtooltip
/startattack
/castrandom Holy Shield, Hammer of the Righteous, Judgement of Wisdom
Button 2 Shaman
Code:
/target [target=focus,help,nodead][target=Coltimar,nodead]
/assist
/cast [nomodifier] Lightning Bolt
/cast [mod:shift] Chain Lightning
Pretty simple, needs a revamp, but works for me atm :/
