Please remove or change the mechanics of this room and/or fight. You have the main objective, Goldstein the Equalizer, sitting on a platform in the middle of the room accompanied by high armor/hp adds that chain knockbacks and knockdowns.
If you attempt to engage Goldstein on the platform, you just get knocked off repeatedly or crowded into a corner where you cannot move.
If you attempt to engage Goldstein from below the platform, you are not able to properly hit him and his adds will just bully you to the ground and/or into a corner.
This is the most frustrating and unfun fight I have experienced in 350+ hours of playing so far. Every other monster in the game having staggers, knockbacks, knockdowns, and grit is bad enough already and needs to be fixed, but this encounter takes it to an entirely different level. I really hope this was a mistake and not intentional game design.
