Changes

* [[Bad Temper]] slows the rate of Fury drain.

* [[Enrage]] gives the barbarian a single orb of Fury and increases the Fury gained and damage taken for a short time.

These three skills are all from the [[Berserker Skill Tree]], but it seems unlikely only that skill tree will have Fury-based skills. It's certain that the skills will evolve greatly over the course of development, but until Blizzard releases more details, players can only speculate.
