HoTF 44 Berserker Fury: When you use a barbarian primal attack power, you enter your Berserker Fury until the end of the encounter. Alternatively, you can use a minor action while you are bloodied to enter the fury.
So I am reading the text and it seems to assume that a Berserker can enter their fury every single encounter. Is this true? How is this not overpowered? Because it only affects certain powers and cripples your defender abilities?
Also, what about regular barbarian dailies? For instance, Behemoth's Rage has the primal keyword, so it triggers Berserker's Fury but do you also gain the benefit of the side benefit, ie THP for all hits? Or does that require the rage mechanic that the berserker doesn't have?
