Rock is largely for mutants. Need Rumbler to deal with Ogrynn squads, Adhesive charge is okay, but i think its not necessary if you can aim the nade launcher well. Very rarely do you need adhesive charge against monstrosity anyways.
Largely using the light Heavy combo to regenerate toughness and inflict bleed. Bull Rush with bleed instantly procs 50% damage reduction so you can front line more effectively. However, cleaver lights are very good in horde clearing and not to be slept on. For other enemies, its largelly the heavy bleed procs that will kill them with sufficient stagger spacing (or using the rumbler in tandem for this goal if assaulted by an elite squad).
Haven't yet decided if this is Auric level. My opinon on most Ogrynn playstyles is that it largely depends how well it synergizes with the rest of your teammates and their playstyles. To that end, I don't there can be an Auric designation for any Ogrynn builds.
Bull cleaver is probably the best for this build, but there can be other members like the Bully club 3. You just need (toughness generator blessing ) + thrust for the melee weapon.
