I use ken's mellee macro from the wiki, with a few modifications of my own. When you get to 44 this can be of real help as it has been to me.

Code:
/follow focus 
/assist [target=focus, exists] 
/startattack 
/cast Hammer of Wrath 
/stopmacro
I use this with "ever more tedious" hammer of wrath. With 5 pallie wailing away, health percentage drops kind of quick; and its hard to keep track. This way any one of the 4 or 5 hammer of wraths may go off, or maybe all of them will go off. But this has been a great option.
