This is a theoretical build I'm working on. Not field tested yet.
Basically the goal is to have constant temp health and to be the front of the pack with your shotgun...without much fear of dying.
Lots of weakspot dmg mid campaign. You're the primary damage dealer afterall. Also.. Who needs to aim down sight when you have a shotgun and want to kill things within a few feet from your face for that temp health replenishment.
Marathon runner is intended to help you navigate with backpedaling and strafing as fast as you walk... Because you always want to move around the battlefield and get into a position to hit weakspots.
