So basically i want to share my own build, Absolute smash hard zeds/boss ez, but since its semi-auto/full auto shotgun you'll need
ATTACK SPEED Bonus from each of your gear/weapons to make this build works well, you'll need at least 50% Attack speed bonus from your
HANDS and
HEAD+
Guns
Side Effect: You'll need to sacrafice Marksman into quickshot to make this build work, so you gotta do close range combat if you wanted to recieve maximum damage persecond. And if you have
EXTRA 5 SKILL POINTS from prestige you can fix it and put 5 Marksman 5 to get 50% Maximum/Minimum Accuracy
Sidenote: If you feel Marksman does not really neccasary then I'd personally suggest
EXTERMINATOR instead marksman Because if you have some Damage VS Infected bonus on your gear/weapons that will do at least 1-3shot Infected
