Your Bald Frontliner Skitarii
 Skitarii Build - Warhammer 40k: Darktide 

Phosphor Blast Pistol is a choice since damage is okay and ammo reserve is quite a lot. You can shoot everything with it in every situation. I prefer Surgical with Infernus to get burn damage overtime to bosses when I couldn't go Chordclaw on them directly. Still Opening Salvo and Surgical are feels better with elites.

Paired Transonic Blades feels very nice with critical chances and a high melee cleave. Rampage because I want an easy to maintain and lot of uptime buff. Spam your light attacks/Heavy/any combo you see suit to clear out horde and Chordclaw is a lot of help too when they're overwhelmed you and your teammates. I use horizontal sweeps sometimes to just CC elites for the team especially when a wave crushers/maulers/ragers is running at you. For bosses I hold my ability to execute Chordclaw Strike instead.

Redline Capacitors because I want extra Chordclaw charge.

I sometimes goes with Power Overflow. Thought it was a waste but it's quite nice with the teammates that's a bit weak despite the condition that your toughness needs to be excess before the node is active. This will help them out a lot when you're able to maintain your own toughness. (I use Overflow Monitor Mod to monitored the numbers.)

Flex nodes to swap out Noospheric Command: Power Overflow, Surge-Extention, Satiated Steel, Slice and Dice, Threat Detection Imperative. (I use Noospheric Command when I feel like my capacitance was a waste to let them sit at 5 charges.) And Weakness Analysis Doctrine is considers able to swap out if you're prefer something else.

For Curios perks, I prefer toughness and health but you're free to swap them out for revive speed and gunners resistance or whatever you're comfortable with. OR you can use 17% toughness, 17% toughness, 21% health/17% toughness, 17% toughness, 3% Stamina.

This build is fun, high survivability and very comfortable to play for me while he can deal okay damage for the team.

I mostly play on Damnation-Auric difficulty since I have no friend play Havoc with. So, I tested this build in these two difficulties only.

Note: I think it's nice to have all rounder build to play when you didn't know what will happen after when you matchmaking to random teammates. You'll be fine with your own for able to clear hordes and elites quickly.
