I have a somewhat similar build. Survivalist, mender seeker mine and reviver hive. Tactical Mk16 with preservation, KSG shotgun with optimist, tactical M1911 with close and personal. Catharsis mask, liquid engineer backpack, picaro's holster, emperor's guard knees, walker and harris gloves and chest with unbreakable. I run this build with a bunch of weapon handling and armor regen attributes, call it my John Wick build. I mostly use it when farming on challenging though cause its not too great on heroic but it's still a lot of fun. Definitely feels more John Wickish than all those one shot pistol builds, imo.
