The Build is designed to be extremely tanky. You have A LOT of Damage Reduction, so just charge right into battle and start doing heavy attacks. Prioritise Elite Enemies where possible and be sure to dodge while attacking. Trappers are your worst enemy, you cannot deflect a net with your charge, so instead, be sure to avoid getting netted.
Dogs are not too bad, but becareful and aware of them.
Your shotgun is practically a sniper so use it liberally if you have a Veteran with Survivalist to restore your ammo.
Last but not least, YOU MUST ALWAYS CHARGE THE BOSS. Get right in there and hold the line while your team takes it out. The only exception is the Beast of Nurgle, draw that in to an easy location and charge it to stun.
