Quite a tough build to achieve. You will have to have almost perfect gear and mods. You can take down most squishy legendary enemies in one clip solo, even with a 4 man team (rushers, basic rifle guys). I've run this during the GE's farming legendary Amherst and haven't had a problem with shield health.
Gloves - Can swap out CHC for EAD.
Secondary - Swap between the cooldown reduction for medbox shield healing and straight up damage with the house.
Pistol - Will need to be a blue one with the proper talents. Only use this to help with your cooldowns.
