Dont worry about the percs. I literally dont know them by memory so I just picked some random ones.
Generally this is my compromise to the broken dream of a big al commanding ls which unfortunately cannot be feasible without 5k ele which would require you to make a huge sacrifice on your fa. This build is honestly much more feasible than a 10k fa lonestar with big al, which I used to use, since you are bringing not just DPS to the team but also constant tact links, which would also from time to time boost the dps of other DPS members of your team.
I mainly use this build for resistance, just like many other sane human beings, and ideally youd want your reclaimer to bring pulse. Just pop the booster then tact and go brrrr. For the first 15 seconds you get the booster dmg boost and proc the competent along with tact link. With this much dmg I doubt if you will need more than 15 seconds to clear a wave assuming that youre half peeking so make sure that the enemies are rushing at you instead of hiding behind cover, in which case you can just pop the flashbang sticky in their face.
dont worry about the chc attributes on the gears. This build is mainly built towards hsd just like most pve builds. ead also works.
if you max out your holster you should get 2926 ele iirc. In order to proc commanding you need 3832 ele.
3832 - 2926 = 906 ele that you would need from the dte mods, which rounds to 182 ele per mod in order to proc the talent. Good luck finding 4dte mods. Hard to find, but certainly not impossible.
kudos to EDR3X for pointing out that HOK is actually great for this build and thus the changes I have made.
