Options to the build.
1. You can replace the purple damage to elite mods with skillpower mods instead, to boost skillpower stat which helps boost the healthpool of your shield when you first activate it.
2. You can roll skillpower stats into health if you switch mods, depends on how comfortable you are with your health and shield health max levels.
3. You can change the Hurried talent on the SMG to Destructive or Deadly instead for that extra punch to damage. If you use a different SMG you can try to also use Responsive talent on the 3rd talent slot. Predatory is a must.
4. You can also switch out stability stats on mods for headshot damage for that extra kick to damage.
5. Secondary and off weapons are your choice.
