It's my 'Wolverine' build I'm working on! I find normal tank builds a touch boring, so I decided instead of going pure armor to push skill tiers on a Firewall build to have both a beefy shield and a powerful drone that can heal me for like 10% a second. My talents help out with this, using Bloodsucker and so on. With the movement buff from my SMG and the reward in damage I get for staying mobile, I go through missions pretty much at breakneck speed even on Hard/Challenging, and as long as I'm smart about when to let my shield regen and use my drone, this, plus my [now 300%] medkits that only have a 50% chance to be consumed all help a ton. The build is still in progress of course, but some pics:
Right now I'm leveling Firewall more and trying to get as much 'Skill Repair' as possible, so I can keep my drone strong while also trading more Skill Tier for armor. As long as my drone ticks for more than 40K/s I'm happy, that's fast enough for my shield to let me tank.
It's a lot of fun for both solo and tanking for a group, so happy to answer if you got any questions! The idea is I chew through the grunts so fast I get like triple armor [and it's very doable thanks to Lady Death and the 1886 I slapped breadbasket on] , then I'm ready to face-tank the bosses. So far, biggest tanking feat was Dragov on Challenging with a sniper friend. I kept him angled so she just popped him again and again in the head, we barely even used the miniguns lol.
And of course, the Flamethrower provides great tick damage.
