So, you've chosen to be a very annoying player, do ya?
The concept is pretty simple.
Just stack as much CHC as you can and try to dish out the most damage. Deadly and Unforgiving on the House for that maximum penetration. The Urban MDR is for long range / group fights, where you can shoot and deal some serious damage. (300/350k per bleed)
You WILL need all the pieces optimized and all the mods almost maxed to reach the 9k STA. It's EXTREMELY important to reach 9k STA. That's your main priority, since most of the damage you will deal comes from the 6 piece ability.
If you prefer the Support Station over the Pulse, just use that instead. The most useful is the Immunizer to counter other Predators / Shock & Burn Turrets.
This build is extremely PVP oriented, so there is no DTE.
Note: Any piece of the equipment can have FA, just one though. 4 pieces on STA, 1 on FA, holster is the Jolly so it doesn't count.
