I can also definitely back-up the Re-Charger/Tenacious Defense combo. I run 2/3 Thin Red Line so I can still health gate. If you have an anointment of “exit iron bear… gain 75% extra shields and health”, when you exit iron bear, you heal up to above the health gate. I use this to reset my health if I’m struggling for healing.
This is also on my mind sweeper build. It feels like it’s great, except for when you shrek yourself with the dropped grenades.
Or flak yourself 
I have been playing with shield/artifact options. Stop Gap/Recharger/Otto Idol/Last Stand – testing which one works best with my play style.
sorry this is a couple days late, but what build are you using? I’ve been trying to create a mindsweeper build, and keep getting sucked back into a DW/BM build with only drowning in brass in SoR
I haven’t settled on one build yet. I might when the new DLC drops because the new COM would help my CoV build.
For this particular build I was using a mindsweeper with recharger. I would go down the SoR tree and avoid health reducing skills then grab Tenacious Defense. I would then go down to put one point in Vampyr. I relied on high rate of fire guns and hit lots from crits. Crits from grenades would also proc Mindsweeper. With all little mini grenades I would stay at or near full health in between recharger/tenacious defense procs. I used a variation of this. It worked out pretty well. Not the best, though.
Thank you for your response. I will give those a try. I also have an a anointed big boom blaster shield that I haven’t used yet.
I will give this a try. I have botH of those items. What class mod do you use?
