Damage-based build with good survivability
I've build running this build for months on Legendary missions and Incursions. The focus is to generate as much damage as possible without being squishy. With this build you will almost always be the one dealing the most damage while being the last one alive. Pulse skill is to build awareness rather than for damage as you're already doing a great deal of damage. Very high stability and accuracy on mods allow you to hit targets without wasting bullets. Reload speed is also important to pump out those rounds and not get caught reloading slowly in a tough situation.
How to Play This Build
The way to play this build is to keep your distance with the Assault Rifle and using the SMG to get rid of rushers by blind firing from cover. Maximum range on the Flashbang sticky allows you to constantly blind enemies and to keep yourself alive if you're overwhelmed. Use Pulse to create awareness and make sure you don't get flanked.
Swap out Recovery link with either Survivor or Tactical depending on the situation.
