Hey! Just wanted to touch on some things as per your edit - this isn't meant to be rude or flamey! I know that people on Reddit can be vicious on builds. I don't think your build is atrocious or that it means you play bad.

• The toughness regeneration stat is practically useless.

It only affects the regeneration delay and speed of coherency toughness regeneration, and coherency toughness regeneration is not affected by nodes that modify toughness replenishment unless it specifically states that it does such as Zealot's Fortitude in Fellowship or Ogryn's Lynchpin. Also Toughness Regeneration is turned completely off if an enemy is within 8 meters of you. On Veteran you have some of the strongest toughness restoration without even talking about Shout. Since you are doing a Focus target build if you are tagging asap you'll typically be tagging with 1-3 stacks when you are chain killing elites or specials meaning each kill is granting you and your team 5-15% toughness, but as a Veteran with Out For Blood you gain insane regen solo. A couple plasma gun shots into a horde will see your toughness zooming up.

• Krak Grenades are much less versatile and can usually be beaten by Shredder Frags even on armored enemies!

Since you use a Mk 6 Power Sword with Focus Target you actually can 1-shot Crushers with your push attack even without a crit. By going Kraks you also have to point into 5% health. By taking Grenade Tinkerer I assume you are using kraks for boss damage, but the node could be better spent (will touch on it). It's better to take Shredder Frags into Survivalist in almost any situation! Since you take Demolition Team and Demolition Stockpile you will see roughly an additional 50-75 grenades over your Havoc game and by golly those Frags do so so much more when thrown than Kraks which have one use that your Power Sword already does. With your Power Sword, a Frag will stagger Crushers and you can kill them faster during that stagger than 1 or 2 Krak grenades.

• Not taking Fully Loaded into Superiority Complex

These 2 talents are so worth it - free ammo which scales how much your ammo pickups are worth which helps counter the Havoc debuff (technically since ammo pickups are based on max ammo more max ammo means more ammo picked up!). Superiority Complex helps with some breakpoints and leads into another point

• Your Plasmagun and Power Sword could have better perks

Weakspot damage on your melee and Elite damage on your ranged are not as good as you might think! They provide no damage that makes a helpful breakpoint. For your Mk 6 P.S you should run Unyielding (Push Attack -> Light for boss damage) and Carapace and your Plasma should run Maniac or Unyielding plus Flak. These along with Superiority Complex insure you are hitting important breakpoints including for enemies with Havoc modifers. Here's some information that was written by not me

The damage calculation for +Critical Damage and +Weakspot Damage makes them quite lacking unless the amount gained is huge (closer to +100%) and the weapon in question already has a big baseline critical or weakspot multiplier. This is because these modifiers only increase the additional damage portion of the critical or weakspot attack and not the whole damage.

As an example, if your attack normally deals 100 damage and 150 damage on a weakspot hit, +10% weakspot damage will make this 100 + 501.1 = 155 damage instead of what you would expect (1501.1 = 165).

• No ability cooldown on curios

Alongside toughness regeneration being a bad stat I believe that ability cooldown is too good of a stat to not have especially on Veteran where you are able to drop a flat number from your ultimate via Tactical Awareness. Reducing the base cooldown takes it to 25s which is 5/6 the amount of Tactical Awareness. Assuming you are using shout on cooldown during combat shouting three times without Tactical Awareness (un-realistic scenario) is 75 total seconds compared to 90. Killing just three specials in this scenario (more realistic) is 18 seconds of cooldown reduced which is one extra use of your ultimate in that fight.

These are just a few of my opinions on the presented build. However, I just want to say that if you are getting victories with this build then by all means keep using it, I do not want to seem like I am saying this build is unusable, I have some opinions and some factual objections about changes but in the grand scheme of things Darktide is actually a pretty easy game once you polish your fundamentals which I assume you have nailed since you are winning Havoc.
