This build is meant for one thing and one thing only. Legendary runs... This will melt any enemies that stands in your way. Everything was thought out and intertwines with eachother. This is built around the DMR and how effective it can be if you can aim for the head. I chose Predator over Striker for this simple fact, bleed damage and also for those who tend to miss, you do not have to worry about getting penalized. The DMR gets an 18% damage bonus for enemies with status effects on them. Shrapnel and Wildfire go great with this since you will be consistently setting targets on fire with your flame turret and bleed when you hit the target ten times. Shrapnel and Wildfire will give you a 30% chance of spreading those effects to nearby enemies. The health on kill will help out since you will be melting enemies fast. You will literally watch gold enemies drop with 3 to 4 headshots. The magazine hold about 64 rounds. I can usually get to 3 to 4 enemies before needing to reload. You might be able to get more depending on your aim and fire control.
