this 1 is probaly best.
i dont use primary gunfighter but greed perk 1 and use either flak jacket or lightweight.
also i wont use a secondary weapon as the battefield should have 1 lying around and use EMP grenade and a sticky .
with scavenger you dont need a secondary weapon btw lol.
if you really want to be bad ass dont use any equipment but use greed perk 3 and either extreme condition, death silence or engineer.
Type 25 - quickdraw, stock.
Skorpion - Fast mag
Hardline, Lightweight, Engineer.
Bouncing Betty, Black Hat.
Overkill, Perk1 greed.
Or something around those lines. Lightweight n stock turns the Type 25 into a long range, high power smg.By having a second, mini smg i can run wherever i want. Bouncing Betty as a granade and Claymore in one.
Engineer takes care of traps. Black Hat for the UAVs. And when defending points i need to have Flack Jacket.
Primary: SMG or Shotgun of choice.
Perk 1: Lightweight
Perk 2: Fast Hands
Perk 3: Dexterity, Extreme Conditioning
My absolute favorite class to play with has that setup + Overkill so I can spawn with both the SMG and the shotgun. That's at the cost of no nades or equipment, but being able to sprint into a room or onto an objective and lay waste with a shotty is much more satisfying anyway.
