I wish the traitors had more impact. Like they could work to sabotage tasks and any money not won is given to them as prize money instead. Sort of a risk-reward thing, playacting to steal away money without giving away that they are traitors.
The format of, someone dies, someone leaves, someone dies, someone leaves just feels a bit bland a few seasons in. Even when they find all the traitors they just add more so it feels like there's no real reward for doing so.
