This is my classified version of Vampire Ninja Striker. It builds the stacks faster, maintains them easier and gains a passive heal. I added HoK to supplement the build’s passive healing and Predatory. The burst healing comes in handy to quickly restore a chunk of health just like damage comes in bursts.
Play aggressive and close to the NPC's. Utilizing cover properly as well makes you very hard to take down. If Recovery Link is down, swap to the secondary and use it until it's back fighting from cover. Alternatively use Flashbang sticky and the secondary AR to spam the stun effect
The flame turret is for crowd control and the support station is for burst healing (drop it, wait at least 10, and pop it). The immunity is nice too when fighting from cover. You could run Booster Shot instead and man the secondary LWM4 as your primary weapon to keep it flowing constantly as well.
For Resistance farming, drop On the Move for Tech Support. This will keep your box (Which you could swap to ammo if you’re farming or leave it if youre going deep) up through the entire wave as you kill. If you have one, a LWM4 with Commanding, Destructive and Determined would work really well with Tactical Link instead of Recovery Link. Use purple electronic DtE mods to unlock Commanding instead of the stamina and firearms ones.
