I can't understand why Knockout was nerfed, it wasn't even close to broken, I loved that perk because it was a huge part of my favorite Melee build, now it doesn't do anything... Previously melee kills refreshed the buff which buffs melee damage and range but now if you kill something with melee it doesn't activate, the change makes no sense especially with the Hunters Combination Blow doing almost the exact same thing but better, and that got buffed.
