Ogryn:
I actually think reworked paul is really good now, in fact thanks to it’s special i gotten better results than with pickaxe and bully club and i see a lot of ogryns in havoc use it too, it might be new meta no one talks about, because with nerf to bleed talent, impact talent, emergence of enemies with rotten armor and blue stims, boost to hp, special of power maul offers great single target damage, along with a lot of instant stagger and crowd control, on max stacks of heavy hitter it attacks almost as fast as bully club, got tolerable non charged combo for single target, got skullcrusher.
Kickback still ok. You can still use one knfie but it’s fallen off, same with branx pickaxe, shovel only blue folding one is decent i feel like, i tried using old one and yellow one, they kinda bad.
Veteran: 2 barrel shotgun, if you use it with WS and auto load talent. Chain weapons became a bit better so they also ok option, shovel too, but you need to put correct blessings on it. Tac axe and combat axe can work too. New weapon is bad. Among ranged: helbore. heaviest version, revolver. Bolt pistol(old model) for grenade veteran. Las pistol. You can also use combat shotgun, but only agripinia.
Zealot: can make any melee work, my favorite is eviscerator, crusher, heavy sword, though this one really fall off significantly against armor, not that it was ever good, but it was tolerable. On the other hand you get strong maniac killer and overall cultists got no chance. Tactical axe good too, model with upward/downward heavy strikes works with stealth. With ranged: i often outside of havoc play with las pistol(if using crit keystone) and shredder. In havoc i used also used revolver, it’s ok if you don’t take knifes. Las pistol viable too for havoc.
Psyker: voidstrike among staffs, las pistol. Among melee aside from force swords, tactical axe is good if you play melee psyker. Bolt pistol with all buffs also decently powerful.
Arbites: Shield, crusher, both great options for havoc and below. Tactical axe works too, combat axe a bit worse but still very usable, at least in auric. With ranged arbites got real bad situation, aside from bolter and bolt pistol if you want to boost dog explosion i don’t see a lot of great options. Executioner shotguns became weaker probably due health increase of scabs, so if you don’t play talents that would boost ranged damage, you will get really mid results. You can use them still, can use shot pistol, revolver, but they not as good as they were.
