After a couple runs trying different runes I decided to check out a Cleave/Rend build similar to what I used while leveling to 60 to begin with. The results were amazing. Cleave was dishing out huge damage to anything in front of me usually critting for 300k-400k a swing while Rend paired with the Blood Lust rune was keeping me topped off but also providing almost too good to be true damage. Whenever I ran into a pack of elites I'd pop Wrath(Insanity) throw up a Rend and Cleave down the entire group in about 5-10 seconds. I could literally stand in a desecration, plague puddle, and fire chain at the same time and stay topped due to the amount of damage I was putting out. Even on bosses where I was only using Cleave on a single target they would melt.
I couldn't even tell you how many act 3 runs I did over the weekend with this build but all I know is I won't be switching out Cleave or Rend for quite some time (maybe play around with a couple different cleave runes). I was lucky enough to find a Windforce, 2x lvl 59 legendary weapons, a really nice pair of Depth Diggers, and found my pretty amazing rare gloves/chest.
If anyone is looking to switch from a WW build to something different I highly recommend giving it a try.
