Here is how I'd change shoulder, "whenever another survivor gets hook shoulder activates for 30/40/50 second during this time the survivor get 5% on unhooking if unhooks shoulder can't be used for the rest of the trial" you have a timelimit and a hard once per trial
People will see this and deadass think it's okay because it doesn't happen in every match so we can let this exist in the game without any nerfs whatsoever
