 Arbites Build - Warhammer 40k: Darktide 

Basically use your F ability when you are about to be hit by a burster and cant push, or you need to tank and fight off a group of maniacs/crushers/maulers - use shotgun to completely annihilate horde aim down sights for easy distance pick offs of snipers.

higher level dog micromanagement:
you CAN get more dps by constantly tagging new enemies with your dog because of the dog pounce + bleeds and stun than if you were to just let him sit on 1 person it does less dps. Also, he can stagger multiple enemies when he pounces so its worth it to learn to eventually micro manage the dog and spam it on nearby groups of enemies for stun/bleeds/DOT electrical damage. Prioritize killing your dogs pounced enemy to make use of your keystones skills: efficient killer/malocater/and not far behind.

you can easily deal with groups of crushers and maulers by utilizing the 'thunder blow' blessing built into the melee weapon, you can keep them perma stunned. having to dodge only when they are on diminshing returns from your staggers.

for missions with blights and rotten armor, due take rebreather talent and instead get rid of rid of impact boost (the +25% to impact talent)

you may ALSO change your curios to curse resist (not grimoir curse resist) if you find yourself struggling with curse on these types of missions.
