Laz Commander
 Veteran Build - Warhammer 40k: Darktide 

Accatran MG Mk II Heavy Laspistol has a base crit chance of 5%, Deadshot gives us 25% and Opening Salvo gives us another 10 for a whopping 40. Reciprocity gives us 25 for 65, the bonus we put on our gun gives us another 5 for 70, and and Desperado gives us 90.  Concentrated Fire can be swapped for any perk you want, I just kept it on so i can hit 100% for the funny

Why 29/30?

Simply put, you're final point can go where you feel like it should for this build. Most of these are my choices personally, but it's very much dependent on you WHAT you want it for. Duck and Dive would give us more stamina regen when we need it by baiting ranged attacks, which is great if you are struggling with getting consecutive headshot kills. You can also take points out of Grenade Tinkerer  and Grenadier if you want, I just like chucking Krak Grenade at people. Kill Zone can boost our base damage if we want to be more risky with our shots and fight in closer quarters. Exhilarating Takedown can give us even more toughness than we are already generating, which when coupled with Born Leader we can support our team even more. Covering Fire cuts the middle man out, if you want Demolition Team whilst still healing allies, take it. Covering Fire will allow you to directly give it to teammates who are actively getting overwhelmed.  Precision Strikes gives you more ranged weakspot damage which is always good. 

It's really up to you and what you want to do personally with randoms or to fit this within your play group. I personally just couldn't decide on the last point for what i wanted to put here and what I think works best because it really just depends on you.

The "Why did you choose this over that?" Choices

Marksman's Focus is needed as Tunnel Vision gives us % stamina back. This might seem weird to mention but remember Deadshot takes a FLAT amount of stamina each second, more stamina = more we get back on crit kill which means we can be more lenient. 

Fire Team is chosen over Survivalist as most people will chosen Survivalist , and auras do not stack. Darktide is a co-operative game and most vets will take Survivalist even in a melee focused set up. If you don't feel comfortable with it then just take Survivalist or Close and Kill. Really this is up to you, I just chose to take the extra damage. 

Krak Grenade  is for deleting crushers and other targets. It also functions as our end all be all button for getting out of bad situations as it can be thrown at your feet when you think you might be getting cornered to create an opening. 

Born Leader is taken over Demolition Team as we can keep our teammates alive by rapidly killing elites and specialists enemies, our pistol can one or two shot most of them.  Confirmed Kill will let us shit out toughness regen by blasting specialists with our Accatran MG Mk II Heavy Laspistol. "But Arina!!!!!!!!!!!!! Born Leader is bad because your team should be shitting out toughness!" Yes, but we generate a lot pretty frequently, it'll mean that when we regen it we can give it out to our team kind of like a mini voice of command. If you really don't like it just swap it so we can get down to awareness. We again can obliterate most specialist enemies in one or two shots, seriously, i've maxed out the buff bar with this build with just Confirmed Kill alone.

Whilst its not included in this build, If you'd like to be more focused on deleting bosses, Executioner's Stance would be nice to swap off for. I've considered doing so as it should(?) allow us to obliterate Beast of Nurgle, but you can also just throw krak at it

Why the Lawbringer Mk IIb Power Falchion ?

I just chose it because its fun to use. You'll rarely need it but use it when you are getting overwelmed. You're las pistol should be capable of tearing through crowds due to its innate pierce. You can take whatever you want really, if you really wanna be "meta" I guess take the Maccabian Mk IV Duelling Sword for deleting crushers without Krak Grenade Our swords isn't meant to deal with big guys. 

Why the Accatran MG Mk II Heavy Laspistol ?

Simply put, it just has higher crit damage. This is by far the most powerful one for a crit build but if you'd like to use any other las weapon you are able to. The recon is also a decent inclusion with its ability to add extra crit chance every non crit, which in theory should slow down how many unlucky shots you have.
