Ogryn didn't die in havoc. He was murdered long before that.

Been playing since launch. Ogryn was my first class and favorite for the majority of the game's lifespan, and I can say with confidence that it used to be the strongest class in the game, but sadly within the last two years, the devs have been steadily leeching away ogryn's capability. They've been tripping him at every turn while allowing the other classes to leave him for orbit.

Once upon a time, the ogryn's combat knives allowed him to move as quickly as other classes when combining it with bull rush. that was removed.

Only a year ago, ogryns had the power to bully bosses off a cliff with the bully club's slap attack or shovel punch, that was removed shortly after zealot received the same ability with chorus.

Mere months ago, a well-built folding shovel could kill multiple crushers with a single downward strike, but that was limited to only one kill per swing while similar options remain for veteran and zealot.

Maybe they want people to stop playing him so they don't have to work as hard on the unique weapons.
