My Ghoulsaw build. This build is about getting enough range to use the stationary Right-mouse + Melee stance which does a large spin of slash damage.
With 9 meters of melee range, you can easily hit enemies around you, build combo very quickly, & apply more & more slash procs & viral.
You could replace [Primed Fury] with [Berserker Fury] if you are able to easily get kills early on (I use [Valkyr] & [Harrow] a lot).
[Blood Rush] is kind of a gimme spot & haven't solidified the best mod to put there yet ([Relentless Combination] was overkill with how quickly combo goes up with your range)
