http://us.battle.net/d3/en/calculator/barbarian#aVQiPT!ZSV!bcbZcb This build utilizes Revenge in tandem with Overpower. Currently the Skill Calculator does not have Elective Mode, so I was unable to list Overpower and Revenge as the left and right click mouse buttons. But they are the primary attacks of this build. The elegance here is that Revenge has no cooldown (perhaps an inherent one; From Beta patch 10 was said to be 1.5 s) and is triggered by getting hit. Using the Tough as Nails passive, this makes it a perfect candidate for Thorns damage. Thorns has been tweaked since Diablo 2, to do a flat damage amount to any monster hitting you. Historically thorns only activated if you took damage, thus stacking Armor (mitigation) and Dexterity (block, dodge, avoid chance) made thorns never work. In Diablo 3, they seem to have done away with "chance to hit" and replaced it with Armor (mitigation), Dodge (mitigation) and Block (mitigation). So you may get hit by a mob, and mitigate all damage associated with their attack, but they would still take thorns damage. Getting back to Revenge, the goal of this build is to get hit. Standing in the middle of a large pack is where you will notice the biggest gains. When Revenge is used, enemies are hit in an AE, and since each mob can heal you, you have the potential to take a serious beat down. Even better, each enemy has a chance to be crit upon, and for each time you do crit, Overpower's cooldown becomes 1 second less. Using Crushing Advance, 30% of a monsters damage gets reflected back to them for six seconds. Thus, there is no need to stack dodge, block or armor for this build. Walk into the fray, and hit Overpower. Chances are some of the crits landed will lower the cooldown a bit. When you are hit by the first mob, he will take 30% reflected damage, plus all of your thorns damage, and has a chance to pop revenge (with Provocation, this is every 3-4 hits). With the ability to attack mobs whenever they charge you, Overpower with Revenge makes this build a fury-free combo that absolutely demolishes waves of monsters at once. Other supporting skills: Battle Rage with Ferocity - since Crit is fueling your Overpower this, is a no-brainer. Each crit increases the duration for this already long buff. Stacking with Ruthless, this gives an 8% chance to crit. When you're hitting waves of mobs at a time, you're bound to crit multiple times per use of Overpower/Revenge, making this buff up almost always. Earthquake with Mountain's Call - This and the Boon of Bul Kathos enable you to have a free Earthquake Cast every 75 seconds. This is perfect for long term boss fights, or if you're dealing with an exceeding number of enemies, you can cast this once your first Overpower/Revenge combo hits. With Earthquake, active you're bound to see crits everywhere, lengthing Battle Range and increasing the times you can use Overpower. Here's where we can see some variation. Currently there isn't a need for a fury generator, except for when you need to use Battle Rage. There are going to be times when Overpower/Revenge isn't worth using (single target monsters, bosses, etc) so a cheap Fury generator is helpful. I chose Bash with Punish for an all-purpose skill, but i'm not convinced it's the best skill. Also as a bonus buff, Wrath of the Berserker is available. This is mainly to stack with Battle Rage and Ruthless to give a whopping 18% chance to crit without factoring in gear. Since Boon of Bul Kathos lowers the cooldown to 90 seconds it makes sense to throw in Thrive on Chaos to increase the duration of Wrath of the Berserker as long as possible. This is potentially an unnecessary buff, and could be replaced with something more utility-based or offensive. Keep in mind, the main goal is to not stack armor, dodge, block, attack speed or movement speed, you want to be hit a lot taking advantage of Overpower/Revenge. Definitely need to work out the kinks, and find the perfect skills for the support slots, but the basis is pretty solid.
