Branx "1-Tap Almost Anything" Big Man Build
 Ogryn Build - Warhammer 40k: Darktide 

Main points: 

• funni stone and not big bonka bomb, cause you ain't got normal means of shooting, and sometimes the bomber just needs to die right now.
• you ain't got normal means of shooting, cause rumbler gives you additional wave clear, if suddenly needed, funny big booms, that stick on bosses and reapers, and booms when you need to stop a group of gunners from shooting for a moment. Also, if you didn't know - alternative rumbler and kickback attacks count as a full Heavy for some reason. While you spam them at ANYTHING at all you continuously bleed them AND you gain insane Toughness. Kinda effective, when you need to dance around for a bit (also, this is actually the main reason you run it, lol, but never mind). You can run kickback, but sometimes you need a little bit of an explosion to make a clearing on the middle of a pack of ragers around a downed ally.
• you take Stamina Regen on trink... curi... shinies, cause you need the stamina to wallop waves around with your Branx Pick Axe, cause the only fully horizontal strike in has is the attack after a push (also second heavy is kinda horizontal, but the key word is "kinda"). You will do a lot of pushing. Cause, first, if taunts spiky punies and they attack you instead of boss, shouty and sparkhead, second, you strike a lot of spiky punies at once (if you make a horizontal rotation with the mouse - even more at once, cause reasons, I dunno, just works like that). I recommend a "push-strike -> normal attack -> push-strike -> normal attack" pattern to not deplete stamina too fast. And HELL NAH, it's not weak against hordes, it's just not mindless Left click spam and takes a couple more seconds to kill them all.
• "Heavy Hitter" is great for you, cause on Damnation the first Crusher in the infamous "Crusher wave" might die in 2 bonks (or more like a bonk and a light strike, tho most of the time - he would, cause Limbsplitter), not one, but after that your heavies just outright smack them for ~3000 damage right into the floor, even on non-weak spot strike.
• Trample or Pulverize - does not matter, but I run Pulverize, cause bleed funni and also gives you Toughness, just cause spiky punies around bleed, and it's Emprah's magic, I dunno.
• You can run "Payback Time" instead of "Get Stuck In", but on higher diffs it's better not to get hit at all, so speed is sometimes the key.
• Do not take toughness nodes, they are useless, despite what "auric pros", that all run the same 3 incredibly boring builds, might say (yes, you, "I run Dumdum Elysian lasgun with a full Death Korps of Krieg skin"). This build (and any ogryn, to be honest) does not need it, you basically do not lose Toughness at all, if you are just wildly swinging your rumbler around. Unless you plan to face-tank sniper shots and 30 gunners at once. Also - health is much better, wounds - even better. More wounds - more chances to get up.
