Pretty solid light attack spam build. You will have taunt up constantly, I use it whenever I have enemies nearby for the toughness regen. I'm not sure if Rending Boost is better than Slam , the extra rending feels really nice for bleed damage but it might be worse. If you do go the Slam route, you can swap to Stay Close! aura when you have another melee ogryn. Stay Close! is really strong now so you could justify taking it even without another ogryn taking Bonebreaker's Aura. Soften Them Up , Payback Time , No Hurting Friends! , and Dominate all buff your bleed damage in addition to the Thunderous blessing and the Skullcrusher blessing on the bully club.
