standard charge-gryn knife/rumbler h40
 Ogryn Build - Warhammer 40k: Darktide 

wave clear is push-attack into heavy, light, repeat from heavy unless you wanna get saucy with blocking for whatever reason

single target is heavy into light, light, repeat

the funny thing is that you can *mostly* get away with just, spamming lights, especially since confident strike is on knife, but you should really be using heavies to proc Beat Them Back, which is pretty good to have (ourghh,, have to think while playing ogryn?? just as bad as ration shortages.,.)

if u see gunners or reapers, charge in and get sloppy with ur knife to get charge back from anything that isnt a grunt, ur generally pretty safe as long as you have anything to hit constantly to keep confident strike juicing ur toughness regen.

if possible, hit C-Spawns when they have a teammate held, or when a P-Ogyrn is pressuring ur team heavily (such as a psyker whos caught out of position, or mid inferno staff blast and cant easily kite away if its putting them in a corner)

basically, hit stuff, but with combos and demoknight charge into gunners or other little batches of elites, ogryn with a bit more thinking

as always, make sure to pay the local dragoness in the cave by the village her tax <3
