EDIT: Build is below. This is designed for PVE though I might try it in sPVP at some point.
The basic idea is to use Hammer as my primary weapon (I love hammers) but instead of focusing solely on defensive support like Taugrim and others, I tried to strike a balance between damage and defense. I went heavily into Strength and Arms to give me some decent crit as well as power and in text the trait Unsuspecting Foe seems like it synergizes really well with Earthshaker.
I took Endure Pain with Frenzy in order to offset the increased damage taken during frenzy, and I would use them in tandem whenever I had the opportunity to capitalize on a disabled opponent. Rifle would be swapped in for bleeds and ranged combat if things became too difficult.
Take note that I’m still fairly new to the game so this might make sense to me now but I don’t know the intricate details of higher levels (only like level 34 atm). Any feedback would be appreciated!
