I would recommend the bleed build on ogryn until you get very good with enough weapons to branch out.
The bleed fixes ogryn’s biggest weakness in melee, armored targets.
Your bleed will cause much more damage than your swings so there is no need to hold the heavy attacks, let them go as soon as the animation goes far enough for it to be a heavy.
I personally have success with the shovel or the shield.
shovel’s 1st heavy does acceptable dmg to armor and its a vertical so you don’t waste it on the horde. I use exclusively heavies against specials, elites, and bosses.
With shield I rotate light => heavy => light => heavy both swings go right to left and are wide sweeping attacks causing the enemy wave to be swept to your left, your light attack causes more damage to trash, but the heavy makes them bleed to give you damage reduction with a later talent. Against specials, elites, and bosses I just spam heavy hits bc they crowd control anything other than a boss so I never get hit by ragers/crushers/maulers.
Talents per lvl
Lvl 5 -smash em good
Lvl 5 talent is toughness on single target heavy attack. This talent allows you to get 20% shields whenever you need it and has helped when a ranged enemy took all my shields and I desperately needed more before the next barrage.
Lvl 10 -blood and thunder
Bleed is your anti armor and your damage reduction.
Lvl 15 Towering presence- more passive shield regen bc of more allies in range.
Lvl 20 Bloodthirst- great damage reduction bc it has more uptime than the other talents in this tier. Don’t focus on keeping max stacks bc if you do then you might be using too many heavy attacks and killing the trash faster by mixing in some lights would be better for everyone.
Lvl 25 -anything other than knife through butter, fully charging a heavy attack is NEVER worth it bc you take too much damage. Always charge your heavy the minimum needed for it to be a heavy, our bleed will do the heavy damage.
Lvl 30 Bull gore- this talent is not for good damage, its to have max damage reduction from bloodthirst.
its a great way for you to charge through a horde to focus down a priority target in charge range and then focus the horde. The damage reduction combined with smash em good should keep your shields up long enough to kill your priority target and turn to face the horde.
I have been playing with 2 hp focused curio’s and 1 toughness curio. Ogryn get damage reduction on both so double dipping doesn’t hurt you.
As far as ranged weapons, controlling longer distance ranged threats is the go to.
Rumbler is a great ogryn weapon if you’re very accurate. A direct hit does great damage and then explodes resulting in dead specials, but if you don’t direct hit they just get knocked down, it gives you a chance to charge or a teammate to finish the job.
Rumbler also clears a horde in emergencies, shoot it at the ground so it bounces in the air bc it seems to affect a wider area if it explodes in midair.
Ripper gun mk VI seems to have the most accurate long range shot out of the ripperguns. Do not aim down sight, the hipfire gets a tighter spread if you are stationary and it fires a 2 shot burst so the crosshairs stay tight. Use aim down sight to burst a crowd mixed with specials or elites.
