This build is specifically for Resistance runs. I call it the burn the world resistance run - It has enough FA and Stam to unlock the talents that require 3832 of those stats, and the rest is dumped in to electronics. As such this is a 4/4/8 build.
The 3 piece FireCrest bonus ( 50% Fire turret range and damage). combined with the 4x 4% turret damage mods will get your fire turret to be a world burning machine. Tech support talent will keep the turret going forever. Rarely will you have to deploy a second turret in a single wave. Boss waves and objective scan waves are the only ones where I use a second turret.
This build has high enough electronics, so the support station can easily handle even the contamination event health regen burden. Always kill the first enemy before dropping the support station. Support station skill power is higher due to talented proc on weapon. Thing to remember - ammo cache support station adds 15% skill haste. This is really not necessary in this build, but useful to know if you are running some other setup.
4 pc tac stacks add 30% SP, so make sure you have this at the end of each wave for the next fire turret.
Tech support and wild fire are necessary talents. Combat Medic and Battle buddy when running in a group. If solo, switch these out to Critical Save and Steady Hands. I like steady hands because you are in cover a lot during resistance runs.
