This build mostly focuses on keeping alive, Frenzy is the main attack, with revenge being used whenever it's up. Wrath of the Berserker, is the main DPS dump, while Furious Charge, Ignore Pain and War Cry are used for defense.
I have not had time to look at optimal builds at this point, but this seem to work pretty good for me. In hell, I was mainly using 2H'ers with full DPS dump to burst down bosses/packs. The gear is mostly what I leveled with, with only the weapon upgraded.
