Ogryn has only one viable weapon and one viable build to use on heresy/damnation, and if you deviate from that build you’re dead weight. It’s also very antifun in a lot of cases because you just sit behind your shield and don’t participate while everyone else gets to actually play the game.
First, his only interesting melee weapon is the shield. The rest is cool but totally useless since enemies with rifles will destroy you.
You have to play on with it, it’s slow, the heavy attack has terrible damage. This need to change, create more weapon with shield, or big melee weapon.
Secondly, he needs a real ranged gun. It’s really hard sometime when you are surrounded by soldiers because when you’ll try to kill them with a certain distance, your weapon lost 90% of his damage.
The only weapon you can use in those cases, it’s the grenade launcher. The rest is cool but only if you are close to the enemies.
Thirdly, Ogryn has big shotguns & a big rifle. But for some reason, they are completely useless against armour.
Those guns have the size of a human, or almost, the bullets are the size of a hand but even with this, you can’t break through it.
I tried the big rifle, the Heavy Stubber, against armour & against boss / mini-boss, it doesn’t no damage. It’s insane, the gun is enormous, bullet are enormous, but it’s only good against horde ? Why ?
Last point, Ogryn is way too dependant to the team.
If you don’t have a veteran or anything else, and you end up in a team with three ogryn, it’s pure pain. Of course, you can finish mission, but it’s really hard to manage all elites, with flamer, rifles, sniper etc.
When I’m in a mission I feel like I’m useless, one veteran can do all the job. I’m not even talking about Psyker, because it’s a one-man army when you have correct weapons & build.
