Build tweak for fractals

[Mikau.6920]

Hey.

 

I have a full Viper Firebrand that I use for Fractals and I want to try a Berserk there. Since I have everything, except a longbow, it is actually cheap to build up (I'm broke, I only have 40 gold). I'm thinking of:

My armor already have Renegade Runes and I don't want to swap them out. Same for the torch with sigil of bursting.

 

I want to be condi DPS with some support (through PS).

 

The questions:

* Should I use other Elite skill? Head Butt, Signet of Rage?

* Should I swap Banner of Discipline or For Great Justice?

* Is Empower Allies better than Burning Arrows?

* Other suggestions.

 

Thanks.
