I suck as ogryn on Heresy+, need advice on how to get better

This is why you have a rumbler/gauntlet. When I say the stubber is a trap it’s akin to why I think the shield is a trap; the opportunity cost of it isn’t worth the loss of the massive utility of the gauntlet/rumbler.

You’re more akin to a conflag staff unchained than you are to a foot knight in terms of overall playstyle.

I wasn’t referring to hitting the beast’s body, you can reach the weak point safely many times.

It’s just advice dude, I’m not trying to debate it. It’s something that works for me and consistently wins me damnation, even with teammates who repeatedly die and whatnot despite all attempts to keep them on their feet. I’d highly recommend glancing at one of the videos, I don’t expect you to watch all of it but it can give you an idea.

EDIT: Meant to comment: I’m 99% sure toughness damage reduction on curios isn’t in the game so take that linked build with a grain of salt. Same for inspiring barrage. While a good amount of the advice I saw from skimming it isn’t bad, well… see above.
