This build is focused around crits and fury of the faithful. With the massive bonuses you stack to crit chance and huge cleave on the heavy sword you will decimate hordes faster than just about anything. Just keep swinging and killing to land crits which charge your fury of the faithful. It will charge so fast that you can spam it every couple seconds to replenish any toughness you lose and keep up a massive attack speed.
Strategy:
If there's a horde charge in with fury and spam light attack. Buffs will build up and you'll be cleaving/critting huge swaths of the horde with each swing. Fury will recharge almost instantly so keep spamming it for attack speed or if you lose some toughness. Dodge around the outside of the horde to do extra dmg with backstabs. Doing this you'll be practically invulnerable from damage reduction and toughness gain.
Pack of gunners/shotgunners? Charge in with fury and blend them for the emperor.
If there are elites and you're not dug into a horde just shoot them. For melee against heavier enemies combo your sword special (high piercing) followed by heavy attack I (overhead strikedown) dodging to their back for extra backstab dmg and repeat until dead.
For monstrosities build up your buffs by cleaving through some horde then block+stab plus the sword special + overhead combo. Or just support your team by blending accompanying hordes to a fine red mist and unloading on the monster with your gun.
Alternatives:This build is really focused around the heavy sword. You could sub pretty much any ranged weapon you feel like. You could swap blood redemption or vicious offering for anoint in blood if you feel you need more ranged dmg.
