// FULLY ANNOTATED NOT A "META" BUILD, although it can be super fun & powerful :D Focuses on turning Billy into a non-stop pressure & team fighting machine. Stay active on the map and snowball each victory into large advantages. DO NOT heavy melee, use Bashdown to reload or greed light melees. Getting parried is almost always a death sentence! And remember to slide, this build has tons of firerate and you don't want to reload or rely on melees to keep up shooting.
