During early development, the Barbarian's passive and active skills were divided into three skill trees: [[Battlemaster_Skill_Tree|Battlemaster]], [[Berserker_Skill_Tree|Berserker]], and [[Juggernaut_Skill_Tree|Juggernaut]]. The [[skills]] and [[skill tree]] systems were entirely revised in 2010, and the active skills were arranged into one large list. At [[BlizzCon 2010]] in October Blizzard revealed the new skill system, with all [[passive skills]] moved to [[traits]]. However, At the [[July 2011 Press Event]], it was revealed that [[traits]] had been changed back to [[passive skills]]. The following is a very quick list of Barbarian barbarian skills, divided into three categories, Fury Generating, Fury Spending and Situational abilities. See the [[Barbarian skills]] page for a more thorough summary, or any of the individual skills pages for full information.
