Personally enjoy running ranged bezerker bow/combistick/plasma caster.
Combistick for that wide area damage and having crazy ranged damage.
Bow takes getting used to, but mixing that up with the caster, makes both of them deadly.
Once you wither the FT down, you can jump in for easy melee kills. At least that’s how I play it out.
If you don’t like ranged, elder sword, large pouch and traps/heals.
Add whatever else you’d like to, but that provides you with a solid foundation to trap the FT long enough to get the jump on a few of them.
Ps. Medic perk on ANY build is solid to get quick heals in (you heal ever game, why not use a perk that helps you do if faster and not have to jump away too far?)
Happy Hunting!
