Since i don't know how to post a link with my build on it i will just tell you
Path of Carnage 14pts
on your knees
Path of Treachery 9pts
elixer of the cauldron
increased pain
Tactics in use
Increased pain
Frenzied mayhem
Brute force
Moral
Sever Nerve
Web of Shadows
Death Reaper
No rank 4 =(
So obviously my set up is similar to Fayze, but i like the Increased Pain tactic, when i first got it it increased my damage on crits from 500 to 800, and that was at rank 24. now i hit for over 1200 most of the time (unless i am hitting a tank, which i try not to do unless i have a lot of backup) and i have even seen 1500 on some BWs
