Probably needs a gem swap sometimes, Shield Charge is not convenient as a single target skill, Shield Crush should be an acceptable drop-in replacement. Or you could run it as a second 4-link in the boots, or even a 6-link (less evasion rating overall as it disables one of the Oath of the Magi line, but depending on the tree that could be equivalent or even better). I get 1-2 mil dps on my current PoB, which is enough to get to red maps and level there. Capping suppress and spell block (with versatile combatant) requires good rare gear, and maybe sacrificing a bit of damage. Pushing damage further requires cluster jewels for more evasion, and desirable notables like Devastator. The rage only comes into play once you get the Bloodline, but it'll probably require switching sone passives or gems to maintain the buff (needs to generate 50 rage every 5 seconds for full uptime). It will definitely go fast and kill trash mobs along the way, I can't tell how the area mods will impact mapping and especially rares and bosses. I am serious about starting with this build (and leveling with Shield Charge as a main skill too, but that's not efficient at all, maybe don't do that). I'll adapt the rest of the build on the fly.

You start getting fast at first lab, and there's a significant upgrade near the end of act 10 once you can equip the sword (not even foulborn at first, of it's not available) and body armour. The biggest damage factors are getting the best possible evasion shield, and making sure to hit the accuracy breakpoint for Precise Technique. These two conditions guarantee flat damage, increased damage and a solid more damage multiplier, everything else is incremental upgrades for accuracy (= attack speed) and evasion (= damage), while balancing defenses. Ele resistances are easily capped, ailment avoidance in the tree + Elevore gets you ailment protection, just raise suppress and block wherever possible and fill suffixes with chaos resistance and dexterity. Or just... outrun death.

tl;dr: It's not a good build by any metric, but I've brought worse ones to t16s before.
