Luca the Cat's 6k Stamina 6 piece Classified Striker build for PvE
53% Damage to elites (can get 5% more if I had 4% DtE mods), most of the end game content you are doing have all yellow bar enemies
15% Health on Kill, with the damage you are getting with this build, you drop enemies quick and you get health in return, even in group play, you have a lot of damage to proc HoK
53% Enemy Armor Damage, Rip away NPCs armor like it's nothing, solid choice for PvE content
Your choice between the ACRs, G36s, or the M4s excluding the Police M4 and the Liberator due to their poor recoil. The talents you want on the AR are Ferocious or Destructive, Predatory, and Determined
Reasoning for Predatory is the same for HoK, you will most likely get the final blow on the enemy and it stacks with the striker healing and a support station
Reasoning for Determined is because it's a great utility talent to get your signature skill back. You are already loaded up on damage from 80-100 Striker stacks, Enemy Armor Damage and Damage to Elites. Also applies to HoK and Predatory, you are most likely to get the final blow.
As a secondary, a Shotgun between the Showstopper or the Black Market/Tactical SASG since it can hold 3 talents instead of 2 like the Showstopper. Talents you want are Responsive, Predatory, Determined or Destructive or Ferocious. A LMG between the Big Alejandro or the MG5 since it can hold up to 3 talents. Talents you want are Destructive or Ferocious, Predatory and Determined.
First Aid Overdose for the "Oh shit, I'm low health" moments and a Sticky Bomb Flashbang to get NPCs out of cover and to stay still
Combat Medic, On the Move, Stopping Power, Steady Hands (Console players) and Tactical Advance
