First of, Im atm AR + Handgun and I love the style of it. But im consider going shotgun cuase of some awesoem abiltys there too :) Atm im doing elites but are moving forword and soon starting to do NM :)
Build I have come up to so for (with a Rifle + Shotgun):
Breacing Shot, Saftey Off, Out for a Kill, Three Round Burst, Red Mist, Suppressing Fire, High Explosive Grenede.
Breach Party, Extra Bullet, Body Piercing, Accuracy, Twist the Knife, Sudden Return, Under the Radar.
With a Handgun, I switchout "Breaching Shot" and "Out for a kill" for "Deadly Aim" & "Big Forty Five"
and "Breach Party" with "Quick Forty Five"
"Breaching Shot" (+ "Breach Party"), worth it?
Builder (pref Rifle builder):
"Saftey Off" + "Extra Bullet"?
"Hip Fire" + "Steady Hip Fire"?
"Three Round Burst" + "Out for a kill"? (if shotty)
"Three Round Burst" + "Big Forty Five"(+"Quick Forty Five")? (if gunny)
"Suppressing Fire"? With "High Explosive Grenede"?
Or just skip AoE with this build and go 100% single Target?
"Red Mist", worth it? Or take "Do or Die"?
"Confuse" as aggro dump? Or a passive?
Maybe "Short Fuse"(+"Final Fuse) instead of "Breaching Shot" ?
Whats worth to take?
"Body Piercing" looks nice with a penetration build.
"Twist the Knife" & "Sudden Return" looks like a must for pen-build.
Whats passive are awesome to go with a Penetration Build thats not goign for crit.
I have seen many guides goo with "Live Wire" but thats for crit. Cant really find a good Elite Passive to grab for this.
