This macro gets a pretty decent amount of dps due to its multi-target abilities. It’s a lot of fun to play with.
I have been lucky enough to get http://www.wowdb.com/items/137052?bonusIDs=3530 so Execute usually ends up as the second strongest dps skill after Mortal Strike with Whirlwind close behind. All three has a cleave function with is really useful in dungeons. I have taken all the recommended talents from Icy Veins except for Sweeping Strikes in the first tier to get more cleave functionality.

The second macro is for burst AOE. I took Warbreaker out of the Cleave macro because you looked like an idiot when it cast Warbreaker first and then Charge, this puts it together with Bladestorm and Battle Cry so maybe its not the most efficient use of abilities but its awesome to watch the amount of crits flying around on the screen.
