Hello there, I'm starting a Brute, mainly to casually level and run solo and some grouping stuff.

My concept wants elec as a primary, I was wondering if I'd be better off with Dark Armor or Firey Armor as a secondary. I've heard FA is a beast with Damage, whereas I've never heard anything good about Dark Armor.

Was just wondering what my options are, any help is appreciated, thanks.
