This is my go to loadout when I want to get any group through a legendary mission (Well, when playing classy Reclaimer gets boring)
How to and what for: Stay alive and keep your team up. Triage is #1, and making sure there's 3 other people to shoot at keeps you doing more
.I often run a House with Deadly and Ferocious, however that is not as fun as Showstopper & Tac link (thunk-thunk-thunk-TONKTONKTONKTONKTONK)
The performance mods should be changed between ally or self heal & more sticky bomb range, as needed.
Also, be overconfident and blame someone playing D3 or Reclaimer if you ever go down.
