The game plan is to use LT assail to headshot distant snipers and disrupt destiny targets while using voidstrike to deal with midrange and heavily armored targets. In hordes without too many elites jump in with the greatsword. Popping shield between the group and gunner lines or popping up around a teammate when a sniper targets them. Only quell when your about to hit 100% because you get damage boosts and damage resist the higher your peril.
Make sure to keep disrupt destiny stacks up and to go for weakpoints, max stacks add 15% damage, 30% crit damage, and 37.5% weakspot damage. With this build you should be criting constantly. Killing marked targets also give you toughness back while speeding you up.
General flow is to help push the frontline like the zealot while disengaging from melee occasionally to get rid of ranged threats and to send orbs through chokepoints. The voidstrike is really good at staggering crushers/maulers so it's good to take a step back to help keep them off the team.
Remember blocks and dodges, this build can block while moving longer than anyone else. When Monstrosities show up try to draw aggro and then use your better block to dance circles around the boss while blocking everything cause most other classes have better boss killing capabilities. Get up in beasts of nurgles faces and put up a shield while keeping them there, it completely negates their vomit and they can't swallow anyone.
For your survivability you should be dodging almost constantly while swinging at head height and anytime you feel like the dodges slowdown switch to blocking for a sec. The sword block attack can stagger anything but bosses including throwing bulwark shields back. This build survives off of dodges mobility the it's kill power to regen toughness.
