Multiboxing 4x Barbarians: Whirlwind builds patch 2.2.1

[Devile]

For keywardens, Barbs are perfect. For Ubers, I think DHs or Wizards.

5th passive? Brawler mostlikely. U won't find many passives that add damage and not having all of them, will hurt your GR times. Most passives are focused on damage reduction and resources. U really cant afford losing those just cause they are not great against single targets. Sure, the RG fight may take less time but maybe it will hurt your clear times to get to the RG in the first place. It's all about trade offs. I rather have Rampage, Berserker Rage, Ruthless, Weapon Master and Brawler. Nerves of Steel if I'm dying, but for GR41-43, those are the 5 passives I prefer.

Once I get decent Hellfires for all 4, I'll go the CDR path and use CotA+WotB.
